Determination of serum proteins in the presence of dextran by means of the biuret reaction. 1977

A Gregor, and E Kostrzewska, and W Godorowska

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.
