Instrument Set-up 3.1 Initial Start-up 1 Place the instrument on a clean, sturdy table or bench. It is important to keep the instrument in a clean, relatively dust free environment to ensure optimal performance. 2 Connect the power cord to the back of the instrument. Before connecting the instrument to the main electrical supply, check that the AC voltage is appropriate for the instrument. 3 Turn on the power switch on the rear panel. The LCD will display the version number of the on-board firmware. After about three seconds, the instrument will perform an initial self-diagnosis that requires about fifteen seconds. The Login Screen will now be displayed for you to choose your user level (administrator or common user), and enter the password (Initial password: 00000). Please allow three minutes for the instrument to warm up (reach thermal equilibrium) before reading plates. 4 Install the printer paper (if the optional internal printer is installed). The thermal printer paper is treated on one side only and must be properly installed for the printer to function. The side of the paper that faces out from the roll is the treated side. a. Open the rear cover of the instrument. b. Tear off a small piece at the beginning of a new roll at an angle to form a point. c. Place the roll of paper in the small pan-like holder positioned below the printer. The roll should be positioned so that it will feed from the bottom. d. While pressing the PAPER FEED key, feed the pointed end of the paper into the paper feed slot in the underside of the printer until the printer grabs the paper and feeds it through the slot in the top of the instrument. e. Securely close the rear compartment. 6 Section 4. Operation 4.1 Instrument Overview The Model 680 Microplate Reader has built-in software that allows the user to set the plate reading and data analysis conditions as a protocol data, read a microplate under the defined reading conditions, and get the printout reports from the internal or external printer. The software communicates through the 4-line, 20-character LCD and is controlled through the instrument's membrane keypad. The display shows the current mode of the on-board software. The software has three different protocol types: End-point analysis, Kinetic analysis, and the Checkmark validation protocols. The user presses the Memory Recall key to select analysis mode passing through the choice of the protocol or the collected data. 7 Operation flow when End point protocol selected Edit Not Use Constant Ranged Cutoff Single Cutoff Control Cutoff Up to 12 Standards 0 to 9999 17 choices 12 choices of curve fit type 4 choices of graph axis combination of Log and Linear Single/Dual Wavelength Shake (Yes, No), Speed (High, Low, Mid), Time Read Speed (Fast//Step) and Read Mode (Normal/Eval) Disable/Enable, Temperature .Func key to switch [N] to [F] [N] for sample number, [F] for sample type .Func key to switch from [ABC] to [abc] to [sym] key to move cursor For current user mode Administrator or Common user Administrator has power to switch Filter wavelength setting for 1-8 positions, “0” for no filter Day/Month/Year, Hour:Min .Func key to switch from [ABC] to [abc] to [sym] key to move cursor SaveSTDC Printer Ranged Cutoff Single Cutoff Formula 12 choices of cutoff formula Ratio Concentration Unit Ranged Cutoff value Cutoff Single Cutoff Report Raw(Raw data), Abs(Absorbance), Lim(Limit), Mtx(Matrix), Cut(Cutoff) Crv(Curve fit), Cnc(Concentration), Dif(Difference) Protocol Limit Upper Limit Lower Limit Number of STD Concentration For Limit Report Unit Standard information Curvefit type Graph axis STDs Curvefit Recall STD Curve Recall Setting Recall Yes/No Selection Select STD Curve 5 choices of memorized STD curve Set Photo mode Mode Set Shaking Set Read mode Incubation Manual mapping Mapping Automatic mapping Blank,CN,CW,CP,CO,QC,Calibrator,Sample,Replicate well Kit name Change password Security Change user Lock/Unlock Filters Date Set Lab name Save STD Curve 5 choices of storage number Rename STD Curve 5 choices of STD .Func key to switch from [ABC] to [abc] to [sym] curve key to move cursor Select Ext.Printer ASCII / ESC/P ASCII / ESC/P Printer Selection for external printer Bold for menu Italic for program pages 8 Cutoff Values setting Gray zone setting when single Cutoff Cutoff Control setting Gray zone setting when single Cutoff Coefficient setting of selected formula 0 - 9999 17 choices of unit Cutoff Values setting Gray zone setting when single Cutoff Operation flow when Kinetic protocol selected Edit Reading Number of reads (2-30), Start delay time (0-999) Inter Reading interval time Mode Shaking Shake (First/Every/disable), Speed (High, Low, Mid), Time Ph.mode Single / Dual Wavelength Speed Read Speed (Fast/Step) Incu Disable/Enable Temperature CC Limit (correlation coefficient limit) Calc.range (calculation range of reading number) for Linear regression Report Protocol Report Security Filters Date Set Lab Name GALT factor k input (0- 9999) Calc Result = (2nd read – 1st read)*k for GALT Report Manual mapping Mapping Automatic mapping Assay Kit name .Func key to switch [N] to [F] [N] for sample number, [F] for sample type General Kinetic or GALT assay assay type selection Absorbance, KINETIC Plots, Linear regression when General Kinetic Assay selected GALT report when GALT Kinetic assay selected For current user mode Administrator or Common user Administrator has power to switch Special Buttons Memory Recall Print Main Blank,CN,CW,CP,CO,QC,Calibrator,Sample,Replicate well Change password Change user Lock/Unlock Save STD Curve Rename STD Curve Select Ext.Printer ASCII / ESC/P 5 choices of storage number SaveSTDC 5 choices of STD curve Printer ASCII / ESC/P Printer Selection for external printer Protocol End point Plate Data Kinetic Checkmark Report Protocol Bold for menu Italic for program pages 1-64 End point protocol storage 1-2 Kinetic protocol storage Checkmark reader test Printout Returns to MAIN screen 9 .Func key to switch from [ABC] to [abc] to [sym] key to move cursor Filter wavelength setting for 1-8 positions, “0” for no filter Day/Month/Year, Hour:Min .Func key to switch from [ABC] to [abc] to [sym] key to move cursor .Func key to switch from [ABC] to [abc] to [sym] key to move cursor 4.2 Functions Overview 4.2.1 Calculations The Microplate Reader uses Beer's Law to calculate the absorbance value of each well. Beer's Law states that absorbance is equal to the log10 of the ratio of the baseline measurement intensity (Io) to the sample measurement intensity (I). Beer's Law Absorbance = Log10 (Io/I) Before measuring the plate, the reader takes a reading for all eight photodiode channels. These values are recorded as the baseline measurement (Io) values for each channel, respectively. The reader then records the sample measurement (I) value for each well, and calculates the absorbance using these values. Channel-to-channel error is significantly reduced because the Io value for a given channel is used only in determining the absorbance of the wells of that channel. 4.2.2 Security password The Model 680 Microplate Reader requires user login with password. This security feature helps to prevent any unwarranted modifications to the analysis conditions/protocols and data stored in the instrument, and identifies operator on reports. The reader has two user settings, the Administrator and the Common user. Each user level has its own security password. 4.2.3 Memory Back-up The battery back-up provides memory even after the reader is turned off. The following information will be saved in the memory until new reading parameters are set by the user or a new plate is read by the instrument. Note that if a run is aborted before it is finished, all the previous plate reading data remain in memory and none of the data from the aborted reading is stored. 1. 10 latest plate reading result for End-point protocol 2. 2 latest sets of Kinetic plate reading result (Max 30 series of readings for each Kinetic) 3. 64 End-point Protocol settings and 2 Kinetic Protocol settings 4. A set of Checkmark reference data and one latest set of Checkmark reading result 5. 5 set of Standard curve data for the storage of standard curves and graphs 6. 8 wavelength values for filters 7. Laboratory name 8. Two security passwords (for the Administrator and the Common user) 9. External printer type (ASCII or ESC/P type) In addition to the battery back-up memory, the instrument has a small amount of none volatile memory to keep the system information after the battery is dead. The Serial Number is stored 10 in this memory. The first time the instrument is turned on, or after a battery failure, the following default information will be held in the memory. 1. Both of Administrator and Common user security password are set to "00000". 2. Laboratory name is "Bio-Rad Laboratories". 3. All wavelength values of the filters are set to "---" nm. 4. The date and time of the calendar chip are set to 1 day, 1 month, 00 year, 0 hour and 0 minute. 5. None of plate reading data is available. 6. End-point protocol is chosen and the protocol number is set to #1. 7. None of Standard curve data for the storage of standard curves and graphs is available. 8. External printer type is set to ASCII type. 4.2.4 Limits The Microplate Reader displays absorbance readings with absolute values as 3.500. Out-of-range absorbance values, i.e. those with absolute values greater than 3.500, are displayed as either "*.***" or "-*.***". For example, if the absorbance is 4.500, then the display will read "*.***", and if the absorbance is -4.500, the display will read "-*.***". 4.2.5 Reports The Microplate Reader can generate nine types of reports for End-point protocol: Raw data, Absorbance, Limit, Matrix, Cutoff, Curve fit, Concentration, Difference, and TeSeE Screening report. And four types of Kinetic protocol can be generated by the reader: Absorbance, Kinetic Plots, Linear regression, and GALT report. Reports of End-point Protocol (1) Raw data report The Raw data report is the uncorrected absorbance values (without blank subtraction). In single-wavelength mode, the reported value is the measured absorbance. In dual-wavelength mode, the reported value is the difference between the uncorrected readings taken with the measurement filter and with the reference filter. (2) Absorbance report The Absorbance report is the blank-corrected absorbance values. The mean absorbance value of all of the wells designated as assay blanks is calculated and then subtracted from all 96 values of the raw data set to produce the Absorbance report. Abs = Raw – Blank mean 11 Blank mean = X/n S.D. = [{X^2 – n*(Blank mean)^2}/{n-1}]^1/2 Where: S.D. = Standard deviation X = Sum total of the raw absorbance for each blank X^2 = Sum total of the squared raw absorbance for each blank n = Number of blanks (3) Limit report The Limit report provides a qualitative YES/NO report. Wells with blank-subtracted absorbance values between the upper and lower limits are represented with an asterisk (*), wells with absorbance values below the lower limit by minus signs (-), and wells with absorbance values greater than the upper limit by positive signs (+). (4) Matrix report The Matrix report provides a qualitative report of the relative magnitude of the absorbance values on the plate. The absorbance range defined by the upper and lower limits is divided into 10 equal partitions, numbered 0 through 9. The blank-subtracted absorbance value of each well is classified according to the partition of the matrix to which it corresponds, and is reported as a signal digit. Wells with absorbance values greater than the upper limit are reported by plus signs (+), and wells with absorbance values less than the lower limit by minus signs (-). (5) Cutoff report The Cutoff report provides a qualitative report of the relative magnitude of the absorbance values or converted concentrations on the plate. Four types of cutoff report are supported as listed below. a. Cutoff Constant Ranged Cutoff Constant The user inputs Positive and Negative values to be used as the cutoff. For units designated "Abs", if the absorbance of a well is within the positive and negative cutoff values, the well is scored "*". If the absorbance of a well is greater than the positive value, the well is scored "+", and if the absorbance of a well is below the negative value, the well is scored "-". For units not designated "Abs", the absorbance value of each well is converted to the concentration value using the curve fit constants of the curve fit report. If the concentration of a well is within the positive and negative cutoff values, the well is scored "*". If the concentration of a well is greater than the positive value, the well is scored "+", and if the concentration of a well is below the negative value, the well is scored "-". Single Cutoff Constant The user inputs Positive and Gray zone values to be used as the cutoff. For units designated "Abs", if the absorbance of a well is within the gray zone value of the positive cutoff value, the well is scored "*". If the absorbance of a well is more than the gray zone value and greater than the positive value, the well is scored "+", and if the absorbance of a well is more than the gray zone value below the positive value, the well is scored "-". 12 Upper cutoff absorbance = Positive absorbance + ((Gray zone/100) * Positive absorbance) Lower cutoff absorbance = Positive absorbance – ((Gray zone/100) * Positive absorbance) For units not designated "Abs", the absorbance value of each well is converted to the concentration value using the curve fit constants of the curve fit report. If the concentration of a well is within the gray zone value of the positive cutoff value, the well is scored "*". If the concentration of a well is more than the gray zone value greater than the positive value, the well is scored "+", and if the concentration of a well is more than the gray zone value below the positive value, the well is scored "-". Upper cutoff conc. = Conc. of positive controls + ((Gray zone/100) * Conc. of positive controls) Lower cutoff conc. = Conc. of positive controls - ((Gray zone/100) * Conc. of positive controls) b. Cutoff Control Ranged Cutoff Control The mean absorbance values of the Positive and Negative wells defined in the plate map are used for the cutoff. The absorbance range of the Positive and Negative is divided into 10 equal partitions, numbered 0 through 9. The absorbance value of each well is classified according to the partition of the matrix to which it corresponds, and is reported as a signal digit. Wells with absorbance values greater than the Positive are reported by plus signs (+), and wells with absorbance values less than the Negative by minus signs (-). Single Cutoff Control The mean absorbance value of the Negative wells that defined in the plate map and the gray zone value that is entered by the user are used to the cutoff. The upper and lower cutoff values are: Upper cutoff absorbance = Mean of negative controls + ((Gray zone/100) * Mean of negative controls) Lower cutoff absorbance = Mean of negative controls – ((Gray zone/100) * Mean of negative controls) The absorbance range of the upper and lower cutoff is divided into 10 equal partitions, numbered 0 through 9. The absorbance value of each well is classified according to the partition of the matrix to which it corresponds, and is reported as a signal digit. Wells with absorbance values greater than the upper cutoff are reported by plus signs (+), and wells with absorbance values less than the lower cutoff by minus signs (-). c. Cutoff Formula The mean absorbance values of the Positive and Negative wells defined in the plate map are used for the cutoff formula calculation. The 12 types of formula supported are: i. k * CNx vii. k + CNx ii. k * CPx viii. k + CPx iii. k * COx ix. k + COx iv. CNx / k x. k*CNx + CPx v. CPx / k xi. (CNx + CPx) / k vi. COx / k xii. k1*CNx + k2*CPx 13 The result absorbance value of the formula calculation and the gray zone value that is entered by the user are used for the cutoff. The upper and lower cutoff values are: Upper cutoff absorbance = Result of a Formula + ((Gray zone/100) * Result of a Formula) Lower cutoff absorbance = Result of a Formula - ((Gray zone/100) * Result of a Formula) The absorbance range of the upper and lower cutoff is divided into 10 equal partitions, numbered 0 through 9. The absorbance value of each well is classified according to the partition of the matrix to which it corresponds and is reported as a signal digit. Wells with absorbance values greater than the upper cutoff are reported by plus signs (+), and wells with absorbance values less than the lower cutoff by minus signs (-). d. Cutoff Ratio The mean absorbance value of the Calibrator wells defined in the plate map and the concentration value entered by the user are used for the cutoff ratio. Before the cutoff, the absorbance value of each well is converted into the concentration value. The ratio of Concentration/Absorbance of Calibrator is applied to the conversion. Then, the cutoff is done with the defined Positive and Negative or the defined Positive and Gray zone values. Ranged Cutoff Control The concentration range of the Positive and Negative is divided into 10 equal partitions, numbered 0 through 9. The concentration value of each well is classified according to the partition of the matrix to which it corresponds, and is reported as a signal digit. Wells with concentration greater than the Positive are reported by plus signs (+), and wells with concentration less than the Negative by minus signs (-). Single Cutoff Control The concentration value of the Negative and the gray zone value entered by the user are used for the cutoff. The upper and lower cutoff values are: Upper cutoff concentration = Positive + ((Gray zone/100) * Positive) Lower cutoff concentration = Positive - ((Gray zone/100) * Positive) The concentration range of the upper and lower cutoff is divided into 10 equal partitions, numbered 0 through 9. The concentration value of each well is classified according to the partition of the matrix to which it corresponds, and is reported as a signal digit. Wells with concentrations greater than the upper cutoff are reported by plus signs (+), and wells with concentrations less than the lower cutoff by minus signs (-). (6) Curve fit report The Curve fit report provides a regression analysis based on the absorbance values of a series of standards. There are ten types of curve fits supported with the onboard software on Model 680 microplate readers: 14 i. 5P Logistic Rodbard ii. 4P Logistic Rodbard iii. 5P Logistic Cook-Wilkenson iv. 4P Logistic Cook-Wilkenson v. 5P Exponential vi. Sigmoid Logistic vii. Linear regression viii. Quadratic regression ix. Cubic spline x. Point To Point regression The onboard software calculates the best fit of the defined curve between each set of two consecutive data points in the standard curve of absorbance vs. concentration. And then it generates the report with the coefficients of regression, the correlation coefficient, and the standard error. For readers with the optional internal printer or with an external ESC/P printer which accepts ESC/P code, a graph of the standard curve may be generated when selected in the report parameter. (7) Concentration report In case of the curve fit, the Concentration report also provides the regression analysis. After the calculation of the curve fit, it calculates the concentrations values of the samples, and generates the report. In case of the cutoff constant with the unit not designated "Abs" and in case of the cutoff ratio, the reader generates the list of concentration of each well. (8) Difference report The Difference report is the subtraction report between the neighboring columns or row. (9) TeSeE Screening report Analysis of the TeSeE screening assay results can be done with two pre-programmed protocols: “TeSeE” protocol is stored in Endpoint Protocol position #5 and “TeSeE eq” is stored in Endpoint Protocol position #6 as factory default setting. Both protocols are locked. TeSeE screening report is generated only if these protocols are selected as current active protocol. Plate is first validated according to negative and positive controls validation criteria; samples are then compared to the calculated cut-off. Criteria for plate validation are set as follow: Criteria #1: Individual Negative Control must be < 0.150 Number of valid Negative Control must be >= 3 Criteria #2: Individual Negative Control must be < 1.400 * Negative Control average Number of valid Negative Control must be >= 2 Criteria #3: Positive Control average must be >= 1.000 Cutoff is calculated as follow: TeSeE: Positive cutoff = Negative Control average + 0.210 15 Negative cutoff = (Negative Control average + 0.210) * 0.900 TeSeE eq: Positive cutoff = Negative Control average + 0.210 Negative cutoff = Negative Control average + 0.090 Samples are interpreted as follow: “POS”: Positive when sample OD >= Positive cutoff “NEG”: Negative when sample OD < Negative cutoff “???”: Gray zone: NEG cutoff =< sample OD < POS cutoff Reports of Kinetic Protocol (1) Absorbance report The Kinetic Absorbance report is the series of absorbance data in the kinetic sequence. (2) Kinetic Plots The Kinetic plots are the absorbance plots of each well in the plate. It is available for readers with the optional internal printer or with an external ESC/P printer which accepts ESC/P code. (3) Linear Regression report The Linear Regression report provides the calculation of Kinetic reaction rate for each well using the linear regression. (4) GALT report The GALT report calculates the following formula for each well between two readings of a plate. GALT = (R2 – R1) * k Where: R1 = Absorbance value of 1st reading R2 = Absorbance value of 2nd reading k = GALT factor 4.2.6 RS-232C Interface The Model 680 Microplate Reader has a built-in bi-directional RS-232C interface (9 pin D-sub connector, Bio-Rad catalog number: 168-1005). This allows external computers to control the instrument. When an external computer is in control of the microplate reader, the printer and the membrane keys, except for the "Start/Stop" key, are automatically deactivated and the LCD display as below. Remote mode The reader will remain in remote control mode until it receives "RL" command from the host computer or until the "Start/Stop" key on the microplate reader is pressed. 16 4.2.7 Printer The Model 680 Microplate Reader has a built-in printer interface connector (25 pin D-sub) or an optional factory built-in printer. The printer interface connector allows the user to connect an external printer for the printout of reports or protocol. This external printer interface is based upon Centronics interface standards. Two types of printer, ASCII type and ESC/P type, are allowable to connect. The ASCII type printer can only accept ASCII character based codes which does not include any graphic codes. Next, the ESC/P type printer can accept ESC/P codes which include graphic codes. The optional factory built-in internal printer and the external ESC/P type printer can generate all types of report including graphs and kinetic plots. 17 4.3 Detailed Operation 4.3.1.
