PCR-PROPDUCT PURIFICATION

[sl6dp at cc.usu.edu]

Going through the literature I have found that it is possible to ream-
plify PCR products directly from the band after selection on a low-melting
agarose gel. I am not sure if I understand it: it is really possible
to run the PCR with a portion af the agarose band, without even
taking the DNA out????. Anyaway, which is a good method for PCR product
purification if I want to run a secon PCR with another primer?, I mean
no comercial kits...Thanks
