PCR Reaction Report

Our group felt well prepared while micropipetting and the pre-lab readings and videos gave us all a proper understanding of how to use the materials. Additionally, a member of our group had experience with micropipettes and was able to provide insight and advice while we performed the lab. We understood the difference between the first and second stop and we were able to use them with relative ease. The final reaction retained the same amount of liquid because we used the pipette to extract all of the liquid in the samples that we had. There was no liquid left in the tubes of DNA samples or the PCR reaction mix. We did not change the label scheme, because it was familiar to us and we saw that it was the most efficient.

Fluorimeter Procedure

Imaging set-up
The first part of the setup was to ensure that the proper PPE was put on. Then the following materials were gathered. A fluorimeter, 3 glass slides, micropipette, pipette holding box, iPhone 6(s). The camera was first set up to find the proper distance and height of the fluorimeter. The iphone was placed into the phone stand and was placed 7.5cm away from the fluorimeter. The fluorimeters height was adjusted by stacking small white boxes underneath it. The height was made so that the camera was directly aligned with the glass slide and had an optimal view of the beam of light. The fluorimeter was turned on and a slide was inserted so that the beam of light crossed directly through two of the circles on the slide. The phone was set on a timer of 3 seconds to take an image, this would occur three times for each sample. The phone was focused on the sample in the slide and the fluorimeter cover was placed on the whole set up. The images were taken while the cover was on and the sample was in darkness.

Placing Samples onto the Fluorimeter

  1. Insert slide into fluorimeter with the rough siding facing upward
  2. The micropipette dial was set to 80 µL
  3. Extract the SYBR Green I
  4. Place the SYBR Green I on the slide in between the two circles where the beam of light shines across
  5. Repeat steps 3 and 4 for the sample
  6. place the sample on top of the SYBR Green I
