Coomassie® brilliant blue R-250

Supplier: Thermo Scientific
Description: Thermo Scientific Pierce coomassie brilliant blue dyes are composed of one of the most common forms of coomassie dye, which is a key component of various colorimetric protein gel stains. Coomassie R-250 and G-250 dyes are two chemical forms of a disulphonated triphenylmethane compound that is commonly used as the basis of stains for detection of proteins in gel electrophoresis and bradford-type assay reagents for protein quantitation. The R-250 (red-tinted) form lacks two methyl groups that are present in the G-250 (green-tinted) form, which is also called colloidal coomassie dye.
