I've seen some people using protein sample buffer containing a pink dye
rather than bromophenol blue. I guess it has some advantages including
that it binds to nitrocellulose. I've seen it mentioned in a Pierce
catalog, but they only sell the whole buffer and not just the dye. Does
anyone know the name of this dye and where I can buy some?
P.S. It also looks cooler than the blue dye :P
