Recombinant human zona pellucida protein 3 (rhZP3), expressed. isolated and purified from PA-1 cells, is characterized for its biological activity and the role in the signal transduction pathway. Characterization of the biological activity of rhZP3 was detected by hemizona assay and immunofluorescence staining of acrosome reaction The results indicated that rhZP3 exhibited an inhibition in the binding assay (HZI 43.6 +/-3.3; n = 9; 30 ng/mL rhZP3) and induction of acrosome reaction (198.6% +/- 77.2% increase from baseline; n = 29; 30 ng/mL rhZP3). It was further confirmed by the transmission electron microscopy that there was no ...
