Hi guys,
I'm trying to design primers in order to amplify only a fragment of a mrna from a cDNA pool and to insert it in a pCDNA. The reverse primer seems great but unfortunately, when I try to blast the forward primer to find other unwanted targets, it finds a lot of cdna which are not the one i'm interested in. I tryed to extend the primer to gain specificity but i don't know if there is a limit in the target annealing temperature.
I hope i explained well the problem
Thanks to anyone who can help me!
