The X-LyzTM Protein Assay Kit is an amine-reactive reagent for the quantitative
determination of total proteins or peptides. The water-compatible reagent reacts
with the primary amines in proteins or peptides to form a sensitive chromophore;
its absorbance at wavelength between 350-405nm is linearly proportional to the
protein concentrations over a wide range (10-10,000ug/mL). The method is
suitable for assays in microplates and test tubes (cuvettes).
