A study of the spectrogram of cupri-potassium complex (Biuret) of the normal and pathological gamma globulin

Abstract

The spectrogram of the cupri-potassium complex (biuret) of gamma globulin is studied in this paper. 72 spectrograms of gamma globulins from human sera and 7 from animal sera are valued. The gamma globulin Solutions have been obtained precipitating this globulin with natrium hyposulfite (Na2S2O3), dialysing against saline solution and final electrophoretic control of its purity. The biuret reagent utilized is Weichsei.- baijm’s and the spectrogram has been obtained with Unicam’s spectrophotometer beginning at 350 mu.
