Coomassie blue dyes are a family of dyes commonly used to stain proteins in SDS-PAGE gels. The gels are soaked in dye, and excess stain is then eluted with a solvent ("destaining"). This treatment allows the visualization of proteins as blue bands on a clear background. Bio-Rad offers Coomassie stains in four formats.
