PCR Cloning - Please Help - Urgent - Cloning using SalI & BamHI site (Sep/15/2004 )

I have used two primers Forward and reverse to amplify my PCR fragment. I have used two restriction sites SalI (in the forward primer) and BamHI (in the reverse primer).

There are the primers:

Cry4BSF: 5’- GGTCGACGTTCATAGGAATCCGTATCA -3’ (27 Mer) - Forward

Cry4BBR: 5’–GGGATCCTCACTCGTTCATGCAAA-3’ (24 Mer) - Reverse

I am not able to clone the product. I saw in the discussion that there needs to be addition of sokme bases. Please help me & tell me that what sort of bases need to be added.

Please help me I am in a urgent condition.

With regards
nimal

You should add plus 3 nucleotides next to the recognition enzyme site.
Cleavage %
2 hr 20 hr
In case of BamHI: cgcGGATCCgcg >90% >90%


SalI: ACGCGTCGACgtcggc 10% 75%
