Possible...yes indeed. BUT the yield will stink especially as the size of
the "peptide" increases. When I try to retreive bands from fixed gels, I
simple apply 40 ma for 48 hrs and electroelute the bands into a dialysis
bag. The big problem that I have found is removing the SDS since my goal
is to sequence it by MS MS
