Coomassie brilliant blue R-250 CAS:6104-59-2

Coomassie Brilliant Blue R-250 is a widely used dye in biochemistry and molecular biology. Its primary application is in the staining of proteins in polyacrylamide gel electrophoresis (PAGE). When mixed with a protein sample and applied to a gel, the Coomassie dye binds to the proteins, allowing them to be visualized as distinct blue bands. This staining technique is essential for analyzing and characterizing proteins based on their molecular weight and relative abundance in a sample. In addition to gel-based applications, Coomassie Brilliant Blue R-250 is also used in protein purification processes to assess protein concentration and purity.
