Trypsin Phospholipase A2 Penetration Zona Pellucida-free Hamster Eggs
2009/2/19
The involvement of a trypsin-like enzyme and a phospholipase A2 in hamster sperm-egg fusion was investigated. Previously acrosome-reacted sperm and zona pellucida-free eggs were incubated in a low...
Rat Testicular Phospholipase A2 Activity：pH Optima, Its Cellular and Subcellular Distribution in the Gonad, and Some Factors That May Modulate Its Activity
rat testicular phospholipase A2 activity pH optima localization control
2009/2/19
A sensitive radiometric assay was developed for detecting phospholipase A1 and A2 (PLA1 and A2) activity. Four to five times more PLA2 activity was observed in rat testes than PLA1 activity. Two PLA...
