Abstract

Proteins from the secretion of rat seminal vesicles were fractionated to yield (i) insoluble protein, (ii) basic proteins (soluble in the presence of urea) and (iii) neutral plus acidic proteins. The first two are necessary for the formation in vitro of a coagulum which is very similar to the copulatory plug. Collagenase-like peptidase from rat testis degrades both protein fractions and prevents coagulum formation.

摘要

对大鼠精囊分泌物中的蛋白质进行分级分离，得到（i）不溶性蛋白质、（ii）碱性蛋白质（在尿素存在下可溶）和（iii）中性加酸性蛋白质。前两种蛋白质是体外形成凝块所必需的，该凝块与交配栓非常相似。来自大鼠睾丸的类胶原酶肽酶可降解这两种蛋白质组分并阻止凝块形成。
