Hi 

I am using PhastGel BlueR coomassie blue dye from Pharmacia, I am concearned
with destaining the gel without losing the signal from the bands (I have
around 10ng protein per band)

I am currently destaining in 10% Acetic acid, this takes quite a long time
and leaves an uneven blue background. I was considering using methanol to
improve solubility of the CB stain. How much methanol should I use without
risking loosing signal from the bands?

Your help is much appreciated!

Regards,

Miguel
