That's right Anne - cut the membrane with your fragment on a small
pieces and then use it in a PCR with your favorite primers. Just be
careful to wash out all the SDS which will inhibit PCR reaction even
at very low concentrations. Also for "crosslinking" might be better if
you just use NaOH rather than UV, but that will not interfere with the
PCR if your amplicon is small.
PS. Sorry to the group for the multiple posts earlier - it is now
obvious that I am using Windows PC....
