No sorry:-) But I've stained pvdf membranes with "Gelcode", and got
Ok results.. (similar to those obtained with amido black staining).
Gelcode is a commercial, one step, gel staining product, and AFAIK
uses coomassie dye. (I could be wrong, as this was in a different
lab and I can;t remeber much about the product).
