Coomassie Stains

Coomassie stains are a popular method of protein gel electrophoresis or SDS-PAGE staining. Gold Biotechnology has both G250 (blue) and R250 (red) dyes available for purchase. These dyes bind to proteins to form a protein-dye complex while the polyacrylamide gels can be easily destained with a mixture of acetic acid and methanol. Mixing G250 with trichloracetic acid without methanol can create a dye in which gel destaining is no longer required. G250 and R250 have a sensitivity of around 30 ng and 100 ng, respectively. Additionally, GoldBio offers a fantastic alternative to traditional Coomassie stains: the Sapphire Coomassie powder kit, which provides an all-included, ready-to-dissolve powder that can be reused multiple times to stain up to 60 gels and is nearly twice as sensitive as silver staining!
