Thank you steve. I did not genomic DNA extraction instead I picked a colony and put it in 10ul ddH2O and used 0.2ul of that as my template. I've got the expected band. I'm gonna do it another time because once I repeat it and no band was generated.
10 X hifi Buffer 2.5 ul
dNTP 1ul
F primer 0.5ul
R primer 0.5ul
mgcl2 2ul
Betaine 6ul
Template DNA 0.2ul
hifi DNA polymerase 0.25ul
ddH2O 12.05ul
Total volume 25ul
Initial denaturation 95°c 3min
Denaturation 95°c 30s
Annealing 54°c 40s
Extention 72°c 90s
Final Extention 72°c 5min

Hello everyone. I have been doing the first PCR for RF cloning for two weeks however I cannot see an expected (at 700 Kb) band instead there is a band at 200 kb. Only once I had 3 bands and one of them was the expected one. I tried it again with the same protocol and no band gained. My primers' TM are 80 and 83 C. I tried different annealing temperatures; 60, 62, 57, 54. F primer: 54 bp and R primer: 45 bp. I would be so thankful if you give your opinion on that.
