title: Determination of proteins in urine by high-performance liquid chromatography with spectrophotometric detection using a pyrogallol red-molybdate complex.
abstract: A high-performance liquid chromatographic method with spectrophotometric detection was developed for the determination of proteins in urine. The proteins were separated on an anion-exchange column and eluted with a Tris-HCl buffer with a gradient of sodium chloride concentration and pH. The separated proteins were mixed with a pyrogallol red-molybdate complex reagent and determined spectrophotometrically. Urinary proteins were well separated without desalting the urine. The reproducibility was satisfactory.
