hello, you can try to clone the PCR product you got from gel in any cloning vector like
pJet or pGem, since they require low amounts of PCR products, then you can digest the vector and get the fragment ready for further cloning. it is two steps more but may help you good luck FH ________________________________ From: DK <[email protected]> To: [email protected] Sent: Sun, December 26, 2010 12:28:15 AM Subject: Re: gel elution of 6KB PCR product In article <[email protected]>, "B.Rama chandran" <[email protected]> wrote: >Dear All, > > I am facing problem in the gel elution of 6KB PCR product, I am >getting very less yield (~10ng/micto liter).

If you didn't have much to begin with, nothing can help. ~50% on gel-extraction are ~ normal. If it is the yield that is poor, try the same protocol with 2 kbp. If the result is good, your kit is not appropriate for 6K. If the result is bad, either your reagents are gone bad/improperly prepared or you are doing something wrong. I've purified 14 kbp from gel with about 30% using Qiagen's kit. Never a problem.
