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. Web27 Jun 2024 · Originally developed in 1985, the BCA assay is another colorimetric assay. (3) This two-step assay first makes use of the biuret reaction, in which the protein backbone chelates Cu 2+ ions and reduces them to Cu + ions. In the second step, the Cu + ions react with BCA to form a purple-colored product that absorbs at 562 nm.
