General description

Coomassie Brilliant blue G 250 (C.I. 42655) is a member of Coomassie brilliant blue (CBB), which is a triphenyl methane dye. CBB dyes are widely used for the visualization of proteins separated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. CBB G-250 (greenish tinted blue) dye is preferably used in Bradford assay for the quantification of proteins.

Application

Coomassie Brilliant blue G 250 (C.I. 42655) has been used to stain gel in sodium dodecyl sulfate-polyacrylamide gel electrophoresis. It has also been used in Bradford protein assay.
