Now the following appears on the display: Press 3, 5, and ENTER to indicate 35 cycles. Accept the zeros in segment 7 and you have terminated the instructions in your file.Ĭhoose the default NO when prompted for Auto Segment Extension by pressing ENTER. When you have finished editing 6 segments, you have created three thermal transition/plateau pairs. * Segment 6 Temp: 72 degrees C Time: 2 min 30 sec * Segment 5 Temp: 72 degrees C Time: 0 min 1 sec * Segment 4 Temp: 55 degrees C Time: 2 min * Segment 3 Temp: 55 degrees C Time: 0 min 1 sec You are now ready to edit segment 3.Įdit segments 3 to 6 with the following parameters: The value 10 sec appears on the display, and when you press ENTER, the display moves to segment 3. Press 1, 0, and ENTER to enter a value of 10 seconds. Press ENTER to accept the 1 minute value and the cursor moves to prompt the seconds parameter. The following now appears on the display: Press ENTER again to accept the default temperature of 94 degrees C for denaturing. After pressing ENTER as above, the following appears on the display:

The second segment is the thermal plateau for the denaturing segment of the reaction. The time parameter now appears on the display:īecause you want the transition to occur as quickly as possible, accept the default values of 0 min 1 seconds by pressing ENTER twice. In this case, simply press ENTER to accept the default temperature of 94 degrees C. You can type the temperature you wish to reach for the denaturing step by modifying the value indicated by the cursor. The following will appear on the display: To edit the first segment: Press STEP to access segment 1. Polymerize 72 degrees C 2 minutes 30 seconds 35 cycles Denature 94 degrees C 1 minute 10 secondsģ. As you press STEP thru the default file Thermo-Cycle file #3, you will edit the parameters of each segment to the ones you desire as detailed in the example below.Įxample: a PCR reaction with the following reaction conditions:ġ. Entering time zero in segment 7 ends the file. 1) and holding the denaturing temperature for the desired time interval (seg. Thus, segments 1 and 2 are a pair, represent ramping of the temperature block to the denaturing temperature (seg. The odd segments (1,3,5) create thermal transitions or ramping of the temperature block to the desired temperature, and the even segments (2, 4, 6) create the thermal plateaus for each of the the three basic steps of the PCR reaction (denaturing, annealing, polymerization). When editing file #3, it is easiest to think of editing segments in pairs. Modification of the default Thermo-Cycle file #3 is a simple way to program a reaction and will be used to explain the machine's operation here. The message or information on the display is what the instrument is prompting for acceptance or change, and the parameter being prompted is underscored by the cursor. When you press the STEP key, the display will take you through the parameters you must answer to modify the file.Ĥ. Edit the default Thermo-Cycle file #3 to conform to your desired reaction parameters as follows. (Other files are accessed by pressing FILE, press the number of the file you want, then press ENTER)ģ. Access the default Thermo-Cycle file #3 from the opening prompt by pressing the STEP key. The cycler will then display the opening prompt:Ģ. Turn the power switch to ON on the front of the machine.

It is strongly recommended that you read these instructions and precautions in their entirety beforeġ. For a more detailed description of the various default files and programs, refer to the Perkin-Elmer/Cetus operating instructions manual.

Step-Cycle(#4) - also a PCR amplification Termination, may be linked to end of cycle file. Soak (#1) - maintains one temperature until file Thermo-Cycle (#3) - a PCR amplification These files can carry out the basic functions of the PCR machine, and they serve as template files which can be modified to program a new PCR reaction or to create user specific files for storage. Files 1 thru 4 are default files which have been programmed with typical parameters. In addition, files may be linked together, allowing for more complex programs or "soaking" at 4 degrees C after completion of cycling when reactions are performed overnight.įiles belong to one of two categories, incubation files or cycle files. These programs can be stored in files which may be modified further for different reactions. A microprocessor allows you to create programs consisting of time and temperature reaction parameters for individual PCR reactions.
