WebAug 10, 2024 · The Lowry assay is an earlier derivation developed by Oliver Lowry in the 1940’s. In a similar fashion to the BCA assay the Lowry assay relies on the reaction of copper ions, produced from the interaction of copper (II) sulfate with proteins present in the sample, with a further reagent. The Lowry protein assay is a biochemical assay for determining the total level of protein in a solution. The total protein concentration is exhibited by a color change of the sample solution in proportion to protein concentration, which can then be measured using colorimetric techniques. It is named for the … See more The method combines the reactions of copper ions with the peptide bonds under alkaline conditions (the Biuret test) with the oxidation of aromatic protein residues.
