Folin lowry assay
WebThe three most commonly used protein determination methods are the Biruet method, Folin (Lowry) method, and the Bradford method. The Biuret assay is the first method, which involves the coordination of a metal ion with successive nitrogen atoms in the polypeptide backbone to produce a deep violet color. Web1. INTRODUCTION. The “Lowry Assay: Protein by Folin Reaction” (Lowry et al., 1951) has been the most widely used method to estimate the amount of proteins (already in …
