Sa. Lopatin et al., A GENERAL-METHOD FOR PURIFICATION OF HUMAN RECOMBINANT SOMATOTROPIN AND ITS MUTANT FORMS BY METAL CHELATE AFFINITY-CHROMATOGRAPHY, Biochemistry, 59(2), 1994, pp. 159-161
A novel scheme for isolation of human recombinant somatotropin and its
mutant forms has been developed. The scheme includes ion-exchange and
metal chelate affinity chromatography. The chromatographic behavior o
f the isolated proteins depends on the amino acid substitutions perfor
