  • The ammonium sulfate is neutralized with NaOH to release

    Biuret Methods 1. Principle: • Biuret Reaction: when a protein is mixed with a solution of NaOH and a solution of copper sulfate, the peptide bonds in protein and peptides form a stable complex with Cu 2+ which shows a violet color. The absorbance is read at 540 nm against a reagent blank. • This reaction requires two or more peptide bonds.
