Method: I tried to follow the protocal listed in the paper that I initially read that uses P2/P8 primers. We used the following concentrations in the tubes | |||
PCR reaction tube: | |||
*2.5ul Forward primer | |||
*2.5ul Reverse Primer | |||
*2.0ul DNA | |||
*1.5ul MgCl2 | |||
*1.5ul PCR Buffer | |||
*2.5ul dNTPs | |||
*1U Taq polymerase | |||
to 25ul H2O | |||
The dNTPs were not added until after the PCR had started. They were added and the reaction was restarted. PCR settings were: | |||
*94C for 1m 30s | |||
*95 30s | |||
*52 30s | |||
*72 30s | |||
*72 5min | |||
This may not be accurate as the reaction was restarted at 66C. This shouldn't be too much of a problem though. The reaction may not work because the fidelity of the Taq may have been reduced due to the reaction going twice. | |||
P2/P8 primers were diluted to make a 100mM/L stock and then a 10mM/L stock was made to have a final dilution of 1:10. When 1ul of the primer is added to 10ul of PCR mix, this is the desired concentration. Also, I used 1U of Taq instead of the 0.5U suggested in the original protocol. | |||
One of the reaction tubes may have had too much master mix added. I marked this tube with an X. | |||
Results: To be determined via agar gel electrophoresis. | |||
