Proacrosin has been isolated from human ejaculated spermatozoa and constitutes at least 90% of the total acrosin present. The total amount of acrosin in milli-international units per million spermatozoa was between 4.4 and 8.9, with a mean of 6.5. This is the first report of the demonstration of proacrosin and the quantitation of total acrosin in human spermatozoa.
前顶体蛋白酶已从人类射出的精子中分离出来，且占总顶体蛋白酶含量的至少90%。每百万精子中顶体蛋白酶的总量以毫国际单位计，在4.4至8.9之间，平均为6.5。这是关于人类精子中前顶体蛋白酶的证实及总顶体蛋白酶定量的首次报告。
