WebINTRODUCTION Hartree-Lowry assay is best for quantification protein in blackbean. Its sensitivity from 150μg/mL to 750μg/mL. This assay has good sensitivity, but require laborious, moreover detergent and chelating agent can interfere. Absorbance at 750 nm. The principle of Hartree-Lowry assay can be apprehended through two reactions. WebLowry assay is a widely used method can detect protein levels as 30-150µg/mL. A protein plays as a relative standard must be selected that provides a similar color yield. An …
