Coomassie® brilliant blue R-250
Brilliant Blue R (C.l. 42660) is a triaminotriarylmethane dye with two amino groups being benzylated and one phenylated. It is also known as brilliant indocyanine 6B and coomassie blue R250. Brilliant Blue R has been widely used for protein band detection after SDS-PAGE (sodium dodecyl sulfate-polyacrylamide gel electrophoresis).
- Its other applications include:
- as a protein stain on epoxy-embedded tissue sections
- for quantitative micro densitometry of protein in sections
- for staining chromatids, actinin microfilaments, developing neurites, and sperm acrosomes
- For detection of protein bands following electrophoresis
