Write a paragraph description for visitors who have no idea what this is) The OpenPCR is a machine that is used to replicate DNA in order to amplify a specific gene. This machine primarily uses changes in temperature and various enzymes to facilitate the replication process multiple times. Experimenting With the Connections When we unplugged (part 3) from (part 6), the screen turned off. Everything on the PCR was working fine expect there was no output on the display. When we unplugged the white wire that connects (part 6) to (part 2), the reading from the screen dropped to -40 degrees Celsius. Test Run (Write the date you first tested Open PCR and your experience(s) with the machine) Protocols Polymerase Chain Reaction We have been given 3 sets of samples of replicate DNA from two patients, to test for cancer makers. We labeled each sample carefully as to not cross contaminate the samples. We also used one positive control sample and one negative control, which contained no DNA,to give us a total of 8 samples. We mixed the samples together with Taq DNA polymerase, MgCl2, dNTP'S, forward primer and reverse primer. We used the PCR machine to replicate the DNA. After the PCR had finished replication, drops of the samples, mixed with syber green, were then placed in a fluorimeter. We used a Samsung Galaxy Nexus smartphone to take pictures of each drop. We then used image j to analyze the drops. Polymerase Chain Reaction Procedure: 1.)We received 3 replicate DNA samples each from two patients and One positive control and negative control sample for a total of 8 samples. The samples we were given were already in their PCR reaction mix form. This mix contained Taq DNA polymerase, MgCl2, dNTP's, forward primer and reverse primer. Each sample was 50 micro liters. 2.)We labeled 8 empty PCR tubes. For the first sample we labeled the 3 DNA samples 1A, 1B and 1C. For the second sample we labeled the tubes 2A, 2B and 2C. For the positive and negative controls, we labeled the tubes + and - respectively. 3.)Using one pipette per sample, to avoid contamination, we transferred the PCR reaction mix we were given to the PCR tubes. 4.)We then placed the samples in the PCR machine 5.)We set our PCR program to three stages. Stage one: 1 cycle, 95 degree Celsius for 3 minutes. Stage 2: 35 cycles, 95 degrees Celsius for 30 seconds, 57 degrees Celsius for 30 seconds, 72 degrees Celsius. Stage three: 72 degrees Celsius for 3 minutes and then hold at 4 degree Celsius. Fluorimeter assembly Procedure: 1.)
