OUR TEAM Name: Tristan Loveday Name: Jeremy Atkinson Name: Kelly Harper Name: Andrew Medina Name: Farah Alyasari Name: Rafael Lopez LAB 5 WRITE-UP PCR Reaction Report The pipetting went fairly smoothly because we took our time to make sure all the samples were transferred properly. We made sure that we understood the difference between the first and second stop on the pipettor before we started pipetting, and there was no visible difference between the different PCR reaction tubes after we were finished. While we were pipetting, we noticed some water on the sides of the tubes with samples and master mix; we tried to use the pipette tip to move these water bubbles down to the rest of the liquid, with which we were fairly successful. At the end, there was a small amount of liquid left in a couple of the master mix/sample tubes; however, the amount of liquid was very small and hopefully had no impact on our reactions. We kept our labeling scheme the same, as our labels fit on the PCR tubes.

It is impossible to distinguish any green color by simply looking at the images. Patient 2 (84174) : 2-1: -1.255978 μg/mL 2-2: -0.13918 μg/mL 2-3: 8.4486 μg/mL The samples from 2-1 and 2-2 are both clear. However, the samples from 2-3 appear green. Conclusions Patient 1 (54502) : All the pictures from patient 1 appeared clear, and two of the samples came out below the negative control value. Every sample was below the positive control value. For these reasons, the patient 1 sample failed to replicate during PCR and is therefore negative. Patient 2 (84174) : Our data for patient 2 appears to be flawed based on the fact that two of the samples came out below the negative control, while one came out far above the positive control. This correlates with the visual appearance of our pictures. Because sample 2-3 had such a high DNA concentration value, it appears to be an outlier that may be the result of contamination. Based on samples 2-1 and 2-2, patient 2's DNA also failed to replicate, and is therefore negative.
