Dye used in bradford assay

WebBradford Protein Assay Introduction Use of the coomassie G-250 dye in a colorimetric reagent for the detection and quantitation of total protein was first described by Dr. Marion Bradford in 1976. Protein binds to the coomassie dye in the acidic environment of the reagent. This results in a spectral shift from the reddish/brown form of Webthe ELISA. The Bradford assay is based upon a shift in the absorption spectra of Coomassie Brillinat Blue G-250 when the dye binds to protein in an acidic solution. Glomalin precipitates in acidic solutions, so this assay must be conducted rapidly (use 5 minutes as the time between adding the dye and reading the samples).
