In this paper a report is made of the chromatographic behavior of growth hormone on columns of carboxymethylcellulose and diethylaminoethylcellulose. Ion exchange chromatography on the synthetic resin, Amberlite IRC-50, has been utilized to purify and to assess the homogeneity of a number of proteins. This resin has been used in chromatographic studies on cytochrome c (l), ribonuclease (2), lys...
