Purification of rat epididymal proteins "D' and "E', demonstration of shared immunological determinants, and identification of regional synthesis and secretion.


Two acidic secretory epididymal glycoproteins, protein D of 27,000 daltons and protein E of 28,000 daltons, have been purified and antisera prepared against each separately. Both proteins were found to share common immunological determinants when tested by double immunodiffusion and tandem crossed immunoelectrophoresis. By selective immunoprecipitation… (More)
