We offer a selection of products for protein staining in electrophoresis gels. We have products for silver staining, Coomassie brilliant blue dyes, and reversible zinc stains.
Our selection of electrophoresis gel stains aid in visualizing proteins and vary in sensitivity, staining time and reversibility. LabSafe GEL Blue™ is an enhanced blue staining dye that is based on Coomassie blue dye that offers unsurpassed sensitivity and rapid band visualization and is supplied in a ready-to-use format that is added directly to protein gels following electrophoresis. FOCUS™ FASTsilver™ silver stain produces crystal clear backgrounds and maximal peptide recovery needed for critical analysis by mass spectrometry. It is also fully compatible with mass spectroscopy analysis. RAPIDstain™, an ultra sensitive and ready-to-use protein stain based on Coomassie staining, is also available and requires no mixing or preparation. It is suitable for native, denaturing, isoelectric focusing, and 2D gels and has a quick and easy staining protocol with protein bands developing in 5-10 minutes.

G-Biosciences Colloidal Blue Stain is a mass spectrometry compatible stain that offers nanogram sensitive detection of proteins. The stain offers ten times more sensitivity compared to classical Cooma..
The fixing of proteins in polyacrylamide gels prevents the diffusion of the proteins, thus keeping protein bands sharp and correctly resolved, and washes away running buffer components that may interf..
