PCR for bacterial culture

1. In a cold PCR tube (Eppendorf), pipet in the presented order the solutions listed in Table 1.
Component Initial concentration Final concentration Example for 50μl

H2O

-

Add to final volume

27.75μl (50μl final)

Tp Green 5X 5X 1X 10μl
dNTPs 10mM 200μM 1μl
MgCl2 - - 4μl
Primer A 1mM 10μM 2μl
Primer B 1mM 10μM 2μl
Culture - - 2μl
GoTaq DNA polymerase - - 0.25μl
DMSO - - 1.5μl

Note: enzyme is added last, and dNTP second from last. 48μl of mixture is inserted in a PCR tube before adding 2μl of culture.

2. Program the PCR machine according to the Table 2.
Cycle step Temperature Time Cycle

Initial denaturation
