Thought I'd kick a little life into an old thread!
"Stains-All" is Cat No. 2718 on PEs list from Eastman Organics. Not that it is any less expensive than anything else but it is fairly well available. You almost never see it listed by the names on the Eastman Organics list, vendors usually list it as "Stains-All." I found the translation on the Sigma-Aldrich website.I've never heard of "Stains All" before - I ain't no stinkin biochemist - but it looks like a good candidate
How well it works I have yet to find out. Hope to report in the next few weeks.
I hope it is soluble in ethanol.
