title: Improvement of the parallel flow dialysis technique for the detection of drug-binding proteins in column effluents.
abstract: The parallel flow dialysis technique was improved for application to the detection of drug-binding proteins in a column chromatographic effluent. To prevent the baseline drift, the pressures of both protein and drug channels were maintained equal during chromatography, and Brij-35 was added to the solvents. The improved method was successfully applied to the detection of methyl orange-binding proteins in human serum and bromphenol blue-binding proteins in rat liver homogenate.
