Jim "anti-kit" Graham strikes again....

How about we set up a string on debunking kits?  Take the magic and
mystery out of them, and the profits away from the supplier...I'll kick
off with Biorad's wonderful blue protein stain, complete with mystery
ingredients (p. 309, Biorad Cat S 1993): their copper stain is probably
nothing more than 0.3M CuCl2, and the destain nothing more complicated
than 0.25M Tris pH 8.0/0.25M EDTA.  Straight off the shelf, and closer
than a phone call away.  Also straight out of C Lee et al., 1987, Anal.
Biochem. 166:303-312.

Have fun,
