PCR with one lone primer and another short

Postby rama12chandra » Mon Jul 18, 2011 3:09 pm

Hiii all ,
I want to do PCR with one long 130mer Reverse primer and another short 30mer forward primer.
I need to fuse His and V5 Tag to my protein, so i have designed those tagged sequences in my reverse primer to amplify the ORF with tagged seqence and later clone it into a vector.
Can anyone please suggest how to proceed with such primer or whether my approach is wrong...

30mer is short? :lol:

Anyway, so that 130-nt primer contains the tag? It does not align whole, right? Cannot you amplify it from somewhere else?

Cis or trans? That's what matters.

Ignore the addition and design you program as if you only had the overlapping sequences and run a normal PCR. A 30 mer overlap is quite long, but why not, too long is not a problem, at worst a waste of (a little bit of) money.
