Figure 1 In vitro matured (SPZ−) and fertilized (SPZ+) (A, B, E, F) bovine and (I, J, M, N) porcine oocytes incubated with a primary antiplasminogen antibody and a secondary antibody conjugated to tetramethyl rhodamine isothiocyanate. Zona pelucida (ZP) was removed by pronase in some oocytes to better observe the antiplasminogen labeling at (C, D, G, H) oolemma and (K, L, O, P) ZP levels. Two pictures (transmitted and fluorescence light) are shown for each sample.

Zona pelucida (ZP) was removed by pronase in some oocytes to better observe the anti-t-PA labeling at oolemma and ZP levels.
