Acrosin inhibitor in extract of the zonae pellucidae of porcine oocytes.
Zonae pellucidae isolated from porcine oocytes were solubilized in 0.15 M NaCl at pH 2.5. The zonal extract contained a protein with relatively low molecular weight, which inhibited the amidase activity of boar acrosin and bovine trypsin. This protein was immunologically related to the BUSI II proteinase inhibitor isolated from bull seminal plasma.
