Umm, how about a thread on how crap most protein assays are?
The protein I work on isn't picked up by the Bio Rad assay at all. It by
chance contains no Histidine. are these two related.
However, coomassie binding (on an SDS PAGE Gel), A280 (method of choice),
and BCA all work well.
any other wierd proteins out there?
