One-and two dimensional SDS-PAGE and Western blotting with monoclonal antibody or peanut agglutinin were used to characterize the glycoprotein,The specificity of the marking agents enabled the study to proceed without purification. EGP was found to include two proteins: one is acidic with a pH of 4.5 while the other is basic with a pH of 8.0 The molecular weights of their subunits are the same, that is 110 kD. This study may shed light on the mechanism of reproductive Process and be helpful to the development of a more cffective culture medium for in vitro culture of early embryo.展开更多
