Western blot on Coomassie stained SDS-PAGE gel?

I'm doing exactly what you describe routinely. Just soak the stained gel
for 30 min in 1% SDS, pH 8.5, then do the electroblot. The nice thing
about that is that you can check the transfer by watching the coomassie
being blotted as well. Up to now, I haven't seen any interferences with
antibody detection.

Best regards,
