Is sperminogen a modified proacrosin? Isolation, purification, and partial characterization of low-molecular-mass boar proacrosin.


Low-molecular-mass zymogen was extracted from boar spermatozoa together with proacrosin using 10% acetic acid supplemented with 10% glycerol, and was purified by the sequential use of gel filtration on Sephadex G-75 and (FPLC) reversed-phase chromatography. LMM zymogen represented approximately 5% of the latent trypsin-like activity present in the sperm… (More)
