The sex steroid binding protein (SBP) of human pregnancy serum was purified to homogeneity by the sequential use of ammonium sulfate precipitation, affinity chromatography on 5alpha-dihydrotestosterone-17beta-succinyldiaminoethyl-(1,4-butanediol diglycidyl ether)-agarose, and preparative polyacrylamide gel electrophoresis. The yield of pure SBP was improved from 5% as originally reported [Mickelson, K. E., and Petra, P. H. (1975), Biochemistry 14, 957] to 34%. Homogeneity of SBP was shown by equilibrium sedimentation ultracentrifugation in 6 M guanidine hydrochloride containing 0.1 M mercaptoethanol which yields a minimum molecular weight of 36 335 +/- 525. The protein is also homogeneous when examined by gel electrophoresis in the presence of sodium dodecyl sulfate. A value of 52 000 for the molecular weight is obtained by this method. SBP partially purified from Cohn fraction IV has also a molecular weight of 52 000 by gel electrophoresis in the presence of sodium dodecyl sulfate; that fraction is contaminated with another protein of molecular weight 90 000 which must be removed to obtain homogeneous SBP. The amino acid composition of SBP isolated from pregnancy serum is presented.
