PURIFICATION OF PEROXIDASE-LABELED ANTIBODY BY USING DEAE-CELLULOSE CHROMATOGRAPHY
ACTA HISTOCHEMICA ET CYTOCHEMICA, 1976 A method which facilitates the separation of the conjugated γ-globulin from both non-labeled antibody and unreacted peroxidase by use of DEAE-cellulose chromatography was shown in this paper. Using the new method of conjugation reported by Nakane and Kawaoi (1974), the isoelectric point of the peroxidase-labeled antibody was found appreciably to shift ...
