Initial Machine Testing

The Original Design

 


Experimenting With the Connections

The PCR machine is heavily dependent on numerous connections and and interconnected parts. This means that, in order for it to work well, everything must be in its proper location and plugged in. This being said, when we unplugged part 3 (the LCD screen) from part 6 (circuit board) of the machine, the connection from the LCD to the circuit board was severed, resulting in the screen turning off. Also, when we unplugged the white wire that connects part 6 (circuit board) to part 2 (core) of the machine, the temperature changed from 26.7 degrees Celsius to -40 degrees Celsius. It is very important that all connections are correct in order to have an effective PCR machine.

Test Run

(Write the date you first tested Open PCR and your experience(s) with the machine)
The Open PCR was first tested on October 10th.




Protocols

Thermal Cycler Program

DNA Sample Set-up

Tube A: Positive Control: cancer DNA template Tube B: Patient 1 ID-16946 Replicate 1 Tube C: Patient 1 ID-16946 Replicate 2 Tube D: Patient 1 ID-16946 Replicate 3
Tube E: Negative Control: non-cancer DNA template Tube F: Patient 2 ID-46296 Replicate 1 Tube G: Patient 2 ID-46296 Replicate 2 Tube G: Patient 2 ID-46296 Replicate 3


DNA Sample Set-up Procedure

  1. Step 1: Fill each reaction tube with 50μL of the PCR reaction mix and label all tubes according to the chart above
  2. Step 2: Add 50μL of DNA sample mix to the corresponding reaction tube (Note: use each disposable pipette tip only once to avoid cross-contamination)
  3. Step 3: Place to reaction tubes into the thermocycler and run the above program


PCR Reaction Mix The PCR reaction mix will contain 8 tubes. Each tube will contain 50μL of the following:

  • Taq DNA polymerase
  • MgCl2
  • dNTP's


DNA/ primer mix

  • What is in the DNA/ primer mix?





Research and Development

PCR - The Underlying Technology

(Add a write-up, essay-style, organized into paragrpahs with descriptive headers, based on the Q&A's from Section three of your worksheet)

(BONUS points: Use a program like Powerpoint, Word, Illustrator, Microsoft Paint, etc. to illustrate how primers bind to the cancer DNA template, and how Taq polymerases amplify the DNA. Screen-captures from the PCR video/ tutorial might be useful. Be sure to credit the sources if you borrow images.)
