Utilizing Bradford Assay for Protein Concentration Calculation

WebThe Bradford method uses the binding of Coomassie brilliant blue G-250 dye to proteins, which results in a dye-protein complex with increased molar absorbance for the determination of protein concentration. The Coomassie brilliant blue G-250 dye is protonated and is reddish/brown with an absorbance maximum of 465 nm at acidic pH. 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. the pro singer\\u0027s vault https://holybasileatery.com
