Purpose of biuret test
WebAmines suitable for this purpose are generally polyfunctional amines in the molar-mass range from 32 to 500 g/mol, ... Examples of compounds available commercially are the isocyanurate or the biuret of hexamethylene diisocyanate. Monomers (e) ... Test results can be documented by photographs or in a chart depending on time. WebPeptides and the biuret reaction. Copper-based protein assays, including the BCA and Lowry methods, depend on the well-known "biuret reaction", whereby peptides containing three or more amino acid residues form a colored chelate complex with cupric ions (Cu2+) in an alkaline environment containing sodium potassium tartrate.
