dull dark purplish to dark grey powder

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.

ChEBI:Carbocyanin DBTC is an organic bromide salt and a cyanine dye. It has a role as a fluorochrome. It contains a carbocyanin DBTC(1+).

Stains-All is a cationic carbocyanine dye and is a multipurpose dye. It stains sialoglycoproteins blueCa2+ binding proteins deep blue to violetproteins red and lipids yellow-orange. It also stains RNA (bluish purple) and DNA (blue).

As little as 3 ng (123 BP fragment) of pBR322/Hae III digest DNA and 90 ng tRNA can be detected on a polyacrylamide gel. PAGE gels are stained in the dark and then destaining by removing the gel from the staining solution and exposing it to the light from a light box until sufficient destaining has occurred. A staining solution is typically made by dissolving the dye in formamide and buffer.
