Hi,
Could someone point me to a protocol for staining Western Blots
(PVDF membranes) with Ponceau-S? I'm currently using Coommassie Blue, but
it takes too long to destain :) I tried a .1% w/v solution of Ponceau
in 5% Acetic acid, but this did not stain well *at all* compared to
Coommassie. A 0.5% wasn't much better. So I washed the membrane with
water and re-stained with coommassie for 5 minutes, and a slew of bands
showed up. Do I just have the conc. of Ponceau wrong? Should I just
dissolve it in water? Thanks in advance,
-John Boswell
