Protein Stains
Proteins in electrophoresis gels can be seen using a variety of protein-specific stains. Bio-Rad offers several sensitive stains that are ideal for classroom use.
Bio-Safe™ Coomassie Stain
By far our most popular stain for research and teaching labs, Bio-Safe Coomassie stain detects proteins in native, SDS-PAGE, and peptide gels without methanol, acetic acid, or other hazardous reagents. Bio-Safe Coomassie stain is a ready-to-use, single-reagent protein stain that produces a linear response, allowing quantitative analysis. Color development is extremely easy. Simply soak the gel in the stain and rinse with water; results begin to appear in 20 min. With sensitivity as low as 8 ng per band, you simply get better results without the solvent waste and toxicity problems of conventional protein stains.
Coomassie (Brilliant) Blue R-250 Solutions
Coomassie (Brilliant) Blue R-250 staining solution is the easiest way to fix and detect proteins in polyacrylamide gels. Ready-to-use solutions are packaged in 1 L sizes and eliminate the need to weigh powders or dilute solutions.
Silver Stain Plus™ Kit
Easy-to-use Silver Stain Plus stain is our most sensitive silver stain. The Silver Stain Plus kit is ideal for both proteins and nucleic acids in polyacrylamide or agarose gels.
