Coomassie brilliant blue G-250

Brilliant blue G is a useful dye for SDS gels as it readily stains proteins with minimal background color. Protein bands can be visualised during staining. It has been used in the Bradford dye-binding protein assay.


A mechanism for dye binding to protein has been proposed, based onmeasuring 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. Recent research reveals CBBG as a P2X7 (P2X purinoceptor 7: P2RX7) antagonist and suggests that it exhibits neuroprotective properties in rat spinal cord cells.
