Biochemistry of the nonhuman primate prostate and seminal vesicles. II. Molecular weights of soluble proteins.

The molecular weights of the soluble proteins from cranial and caudal prostate and seminal vesicle tissues of several species of nonhuman primates were separated by electrophoresis. The tissues of animals belonging to the genus Macaca were found to be similar and are compared to those of other species. The molecular weights of these proteins are discussed with regard to known concentrations of prostate and seminal vesicle proteins.
