DETERMINATION OF PROTEINS BASED ON THEIR RESONANCE LIGHT SCATTERING ENHANCEMENT EFFECT ON SODIUM DODECYL BENZENE SULFONATE

ABSTRACT A novel assay of proteins with the determination sensitivity at nanogram levels has been set up by using a common spectrofluorometer to detect intensity of resonance light scattering (RLS). In an acid aqueous medium, the interactions of Sodium dodecyl benzene sulfonate (SDBS) with different proteins can result in obviously enhanced RLS signals. With the enhanced RLS signals at 470.0 nm, proteins, including bovine serum albumin (BSA), human serum albumin (HSA), α-chymotrypsin (Chy), lysozyme (Lys), can be determined with the limit of detection below 58.1 ng/ml. Synthetic samples and human urine samples were analyzed satisfactorily.
