Two human serum proteins, corticosteroid-binding globulin (CBG) and sex-hormone-binding globulin (SHBG), were purified to homogeneity by the application of a combination of three different modes of chromatography. Human pregnancy serum was fractionated with ammonium sulphate. SHBG (50% pellet) and CBG (80% pellet) were then purified by affinity chromatography on tresyl-activated Sepharose with 15-aminopentadecanoic acid (for SHBG) and 1,12-diaminododecane (for CBG) as spacers and 17 zeta-aminoethyl-5 alpha-androstan-3 beta,17-diol (for SHBG) and 17 alpha-hydroxy-4-androsten-3-one-17 beta-carboxylic acid (for CBG) as specific ligands for these two proteins. The eluate was injected into a Mono Q anion-exchange column. Fractions containing SHBG or CBG were finally purified by liquid-liquid chromatography on Lipar-Gel 750. This chromatographic sequence clearly separated SHBG and CBG from other proteins, mainly serum albumin, without a loss of protein or binding activity.
