PCR Reaction Report
When pipetting the samples, our group did not run into any issues. This was in part due to the pre-lab reading, which explained in detail on how we were to go about pipetting the samples without making errors. The pre-lab reading also helped us understand the PCR process and allowed us to calibrate the PCR device, which included the steps and temperatures of each step of the PCR process. The first stop of the pipettor was to vacate air and to prepare for the correct amount of liquid. The second stop was to make sure that all of the liquid taken up by the pipettor has left into the desired tube. The final reactions had the same amount of liquid because the micropipettor was very specific as to how much liquid was put into each tube. No liquids were left behind in the tubes where the DNA samples and PCR reactions mixed. Our labeling scheme followed that of the PDF file for the lab; nothing needed to be changed.
Fluorimeter Procedure
Smart Phone Camera Settings
- Type of Smartphone:Samsung Galaxy S6
- Flash:No
- ISO setting:0
- White Balance:0
- Exposure:0
- Saturation:0
- Contrast:0
Camera set-up
- Distance between the smart phone cradle and drop = 5cm
Placing Samples onto the Fluorimeter
- Place 80 microliters of SYBRI onto the glass slide
- Add the specified concentration of the 2X Calf Thymus DNA Solution to the SYBRI.
- Align the blob of liquid with the blue LED light so that it is focused to the middle of the black optic fiber on the other side of the blob.
- Repeat steps 1-3 for each of the 6 concentrations.
