Fig. 4. Mouse, but not human, ZP2 is cleaved following fertilization.
Immunoblot of eggs (lanes 1,3,5) and two-cell embryos (lanes 2,4,6) from
wild-type (referred to as `normal') (lanes 1 and 2), huZP2 rescue
(lanes 3 and 4) and huZP2 transgenic (lanes 5-6) female mice. After
SDS-PAGE run under reducing conditions (5% ß-mercaptoethanol),
immunoblots were incubated with monoclonal antibodies specific to the carboxyl
fragment of mouse (faux colored green) or human (faux colored red) ZP2 and
visualized with a secondary antibody and chemiluminescence. Molecular masses
(kDa) are indicated on the left.
