The considerably small size of protein macromolecules makes identification and quantification of unknown protein samples particularly difficult. Several reliable methods for quantifying protein have been developed to simplify the process. These methods include Warburg–Christian method, Lowry assay, and Bradford assay (all of which rely on absorbance properties of macromolecules). Bradford assay method uses a dye to bind to protein.
