What is STAINS-ALL?

Chemical properties

dull dark purplish to dark grey powder

The Uses of STAINS-ALL

Stains-all is an ideal dye for the visualization and identification of proteins on polyacrylamide gels because it differentiates between highly acidic proteins which stain blue and less acidic proteins which stain pink. When employed on polyacrylamide gels, the intensity of Stains-all can be increased by the addition of silver nitrate. It is a useful nucleic acid and protein stain.

What are the applications of Application

Stains-all is a useful nucleic acid and protein stain
