Coomassie Brilliant Blue G-250, MP Biomedicals™

Description

Useful dye for SDS gels as it readily stains proteins with minimal background color

• It is a protein stain in electrophoresis.
• It 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.
