Determination of protein using biuret reagent
WebThe simplest and most direct assay method for protein concentration determination in solution is to measure the absorbance at 280 nm (UV range). Amino acids containing … Webvortex mixing has been eliminated. A protein sample is mixed with the Biuret Reagent and later with Folin and Ciocalteau's Phenol Reagent. The absorbance is read at a suitable wavelength between 550 and 750 nm (maximum color is observed at 700–750 nm). Protein concentrations are determined from a calibration curve. Components
