Site-Directed Mutagenesis

We choose plasmid psb1a3 to be the vector that ligate GPF and RFP fragments.To protect the structural integrity of the constructed plasmid, we need to mutate a restriction enzyme cutting site named Pst I to Afl II. Proper primer are designed for this purpose.



1. Prepare the sample reaction as indicated below:

Total: 25μl

+ 0.25 μl of Ex Taq polymerase(酶的公司名称)

+ 2.5 μl of 10× Taq reaction buffer

+ 2.0 μl of dNTP(2mM)

+ 1.0 μl of template

+ 1.0 μl of oligonucleotide primer P1

+ 1.0 μl of oligonucleotide primer P2

+ 18.25 μl of ddH2O

2. Set thermocycler temperatures and the time. Procedure on the thermocycler are listed below:

① 94˚C for 5 min

② 30 cycle

a. 94˚C for 1 min

b. 55˚C for 1 min

c. 72˚C for 1 min20sec

③ 72˚C for 10 min

④ 4˚C for stock
