Description and Uses

Stains All is a useful stain for differential nucleic acids and proteins.

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.
