stripping buffer! - didn't strip after 30min (Nov/28/2008 )

this was my first attempt to ever use any stripping buffer and it did not work out. to be honest I have no experience with it whatsoever. I used a commercial stripping buffer to strip my membrane after BCIP/NBT visualization but i couldn't remove the stain at all. I added 20ml to the membrane and left it on a rocker for 30 min but it did not strip my secondary antibody to give me a clear membrane to re-treat with another primary antibody.

how do you guys do it usually?

what is the temperature when you did your stripping? I usually did it at 50 oC

BCIP/NBT is not to strip with classical stripping buffers as it is a precipitated colored substrate; stripping buffers are used to get rid off the antibodies;

I propose to strip the antibodies and then to bleach the blot (I would start with 3% H2O2)

thanks The Bearer, but if I bleach the membrane I won't be losing any protein, right? will it just remove the antibodies and the stain?

stone757, I did it at RT
