title: Variability of acrosin inhibitors in boar reproductive tract.
abstract: A new acrosin inhibitor with a relative molecular mass of about 8000 was isolated to apparent homogeneity from ejaculated boar spermatozoa. The inhibitor is effective against boar acrosin and bovine trypsin. It interacts with polyvalent antibodies against the acrosin inhibitor from boar seminal plasma, but differs from all known acrosin inhibitors in its amino acid composition and N-terminal sequence.
