Pink Dye in Protein Sample Buffer

[Vincent Solomon]

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
