Coomassie Brilliant Blue G-250 is a protein stain in electrophoresis. Brilliant Blue G has been used in the Bradford dye-binding protein assay.
A mechanism for dye binding to protein has been proposed, based on measuring Coomassie Brilliant Blue G-250 (CBBG) absorbance spectra during titration of the dye reagent in the absence of protein and its response to different polyamino acids. Brilliant Blue G has been used for determining critical micelle concentration of detergents. It is a P2X7 purinergic receptor antagonist.
