OUR TEAM Name: Ally Coen Name: Jose Loya Name: Monica De La Cruz Name: Christian Cuciniello LAB 5 WRITE-UP PCR Reaction Report The pre-lab helped the group understand the process of pipetting the samples to set up the reaction. It's a simple process to run a fluorimeter analysis but also requires the small details to be in place such as making sure you have the camera about 4cm away from the drop, placing a 80uL drop of SYBR green I solution on the smooth side of the slide, placing 80uL of your sample on top of the drop of SYBR green I, and making sure to place the light directly in the middle of the drop. It was also useful learning to use the first and second stop of the pipet. The first stop allows for the exact liquid to be collected by the pipet from the sample that you selected, but if you go beyond that point then you lose accuracy. We also had to make sure to place any writing on the side of the tubes we used for our PCR reaction mix that way we wouldn't run any risks of losing our labels during the heating process of our PCR. We did have about 20uL of leftover PCR reaction mix since we only took about 80uL of our 100uL volume. Fluorimeter Procedure Imaging set-up Place the fluorimeter on top of a two plastic boxes provided in BME lab. Set up the phone cradle 6 cm away from the fluorimeter. Check to make sure that the camera is at a 90 degree angle from where the drops will be placed. Disable the flash on the Camera. Placing Samples onto the Fluorimeter Set a pipettor to 80 microliters. Place 80 microliters of SYBR GREEN I inbetween the two middle dots of the first two rows. Add 80 microliters of either a calf thymus dilution, or PCR sample to the drop made in step 2. Once the sample is captured remove the dot with a pipettor and discard the waste. Shift the slide back two rows for the next sample and repeat from step 2.

Therefore, we can say that our patient is negative for the SNP disease. The PCR results for this patient were closer to the negative control when compared to both the positive and negative controls. Patient 98829 : The droplet showed to be clear after the SYBR Green was added and there was no green light detected when positioned the the LED light beam. Therefore, we can say that our patient is negative for the SNP disease. The PCR results for this patient were also closer to the negative control when compared to both the positive and negative controls. Conclusions Patient 57569 : This patient tested Negative for the single-nucleotide polymorphism (SNP) disease. Patient 98829 : This patient tested Negative for the single-nucleotide polymorphism (SNP) disease.
