Lowry method protein

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 … Meer weergeven 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. The Lowry method is based on the reaction of Cu , … Meer weergeven • Biuret test • Bradford protein assay Meer weergeven • A simplification of the protein assay method of Lowry et al. which is more generally applicable Meer weergeven WebSimulation courtesy of:vlab.amrita.edu,.
