All tubes have the same forward primer and reverse primer A strip of empty PCR tubes Disposable pipette tips: only use each only once. Never reuse disposable pipette tips. If you do, the samples will become cross-contaminated. Cup for discarded tips Micropipettor OpenPCR Machine: shared by two groups PCR Reaction Report Our team had an easy time pipetting the samples to set up the reactions. The pre-lab reading was very helpful in understanding the procedures we performed today, as it showed visually and audibly how to pipette solutions. By knowing how the lab was going to function, we had an advantage in the execution and understanding of the procedure. In our group, Mia and Michelle pipetted the solutions for Lab C. For Lab D, Gabe and Damian pipetted the solutions. We were able to easily understand the difference between the first and second stops on the pipettor. The final samples all contained the same amount of liquid. There was not any liquid left in the tubes that the DNA samples and PCR reactions were mixed in. We did not change our labeling scheme for our test tubes. Overall, the pipetting was relatively simple and easy, because the group was knowledgeable on the proper technique from the pre-lab reading and quiz. Fluorimeter Procedure Imaging set-up To capture images from the flourimeter, a smartphone with decent camera quality needs to be placed in the phone cradle directly opposite from the light beam from the light box. If possible, the flash should be inactivated, the ISO should be set to above 800, the white balance should be set to auto, the exposure and saturation should be set to the highest setting, and the contrast should be set to the lowest setting. Using the micropipettor, place a 160mL drop of water in between the first two rows of your slide. Switch the excitation light on for the blue LED. Turn on your cell phone camera, turn off the flash, set ISO to 800 or higher, set white balance to auto, change exposure to the highest setting, set saturation to the highest setting, and finally change contrast to the lowest setting. Set your smartphone in the cradle with the camera facing the slide. Adjust the fluorimeter using the plastic trays so that the camera takes a picture of the drop sideways. Adjust the smartphone so that it is as close as possible to the drop, while still remaining in focus. Record the distance between the smartphone and the drop using a ruler. Placing Samples onto the Fluorimeter Using the micropipettor, place an 80 microliter drop of SYBR Green I in the middle of the first two rows of the slide. Add 80 microliters of calf thymus solution to the drop to form a sample. Align the drop so the blue led is focused. Set a timer on your camera to take a picture after the light box is lowered. Take three pictures of the drop. Remove the box, repeating the steps for the rest of the calf thymus DNA. Be sure to take three independent pictures for each sample for accuracy.
