OUR TEAMLAB 1 WRITE-UPInitial Machine TestingThe Original Design
When we unplugged the wires from the circuit board, the display screen on the machine turned off, resulting in the PCR Machine not being able to function and the data being unable to read. Unplugging the white wire that connects from the circuit board to the heating block caused the temperature on the screen decreased 60°C to -40°C. This wire must be the temperature regulator and without this essential part the machine can not read temperatures correctly.
Test Run First tested 10/23/13. As the machine went through the cycles, the temperature was changing according to the numbers that were inputed into the computer. Also the temperature on computer screen was the same on the PCR Machine throughout all the cycles. Overall the machine ran smoothly and completed the 25 test run cycles resulting in it being passing mark.
ProtocolsThermal Cycler Program
DNA Sample Set-up Procedure We will use the following heating and cooling protocol: It will denature at 95°C for 30 seconds. There is a final step at 72°C for 3 minutes.
PCR Reaction Mix
Research and DevelopmentWorking on it..... PCR - The Underlying Technology PCR Components and their Function The PCR (polymerase chain reaction) technique requires the following main components: template DNA, primers, Taq polymerase, magnesium chloride (MgCl2), and deoxyribonucleotides (dNTP’s). The DNA template contains the target DNA sequence that a researcher wants to amplify; the DNA sequence can be from an individual, animal, plant, or microorganism. Primers are tiny segments of DNA that bind to a specific site (i.e. on either end of the single-stranded DNA) of the target DNA sequence to initiate the replication of the target DNA sequence. Two primers are usually used in a PCR experiment so that one primer will attach on the top of the DNA strand while the other primer will attach to the other end. When primers are done binding to the DNA strand, a specific type of enzyme called Taq Polymerase is activated. This enzyme helps to helps synthesize new strands of DNA that are identical to the target DNA sequence. A buffer called magnesium chloride (MgCl2) is added to the PCR tube to stabilize the DNA strand. Lastly, deoxyribonucleotides such as adenine (A), thymine (T), cytosine (C), and guanine (G) are basically the building blocks for creating new strands of DNA.
Steps of Thermal Cycling
(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.)
