title: Patterns of human epididymal fluid proteins on polyacrylamide gel electrophoresis.
abstract: Proteins were analysed by sodium dodecylsulphate polyacrylamide gel electrophoresis in fluid taken from six epididymal regions in 10 men undergoing microsurgery to bypass epididymal obstructions resulting from various disorders. Some major proteins common to most samples were identified with apparent molecular weights of 95, 67, 56, and 44 kilodaltons. A degree of regional specificity in the synthesis and secretion of epididymal proteins was indicated. There appeared to be no correlation between protein pattern or the abundance of individual proteins and the cause of obstruction, although methodological constraints may have partially obscured any such relationship.
