nested pcr

Postby shuk08 » Tue Oct 06, 2009 12:29 pm

How to get rid of larger non-specific bands appearing in 1st round of pcr just above the expected bands (of approx. 1.5 kb)? The non-specific bands from the 1st pcr are amplified in 2nd round of pcr using nested pair of primer.

Are you asking or just saying us?

Cis or trans? That's what matters.

I had the same problem before. I advice you to use an adjuvant to improve your PCR effeciency. I used Q solution that comes with hotstar PCR master mix and it gives me a very good amplicon.
