Determination of Serum Proteins in the Presence of Dextran by means of the Biuret Reaction

Abstract

264 biuret reagents for total protein determination in serum containing dextran were investigated. The usefulness of the method is dependent on proper ratio of the components of the reagent: concentrations of NaOH and copper sulphate, and the ratio of sodium-potassium tartrate to copper sulphate.
