WebJan 29, 2024 · The Bradford protein assay is one such protein quantification method. The assay is named after Dr. Marion Bradford, the scientist who developed the assay in 1976. …
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). WebThe BCA assay primarily relies on two reactions. First, the peptide bonds in protein reduce Cu 2+ ions from the copper (II) sulfate to Cu 1+ (a temperature dependent reaction). The amount of Cu 2+ reduced is proportional to the amount of protein present in the solution.
WebMar 1, 2013 · The Bradford assay is a simple method for protein quantitation, but variation in the results between proteins is a matter of concern.
