Abstract
Zonae pellucidae were isolated from oocytes obtained from rabbit and porcine ovaries. Antisera were prepared in rabbits against heat‐solubilized porcine zonae and in guinea pigs against intact and heat‐solubilized rabbit zonae and against purified rabbit zona proteins isolated from two‐dimensional electro‐phoresis gels. These antisera were used in radioimmunoassay studies to show cross‐reactivity between porcine and rabbit zona antigens. Immunoelectrophoresis studies also demonstrated the immunochemical cross‐reactivity between two distinct antigens of rabbit and porcine zonae. These two rabbit zona antigens were demonstrated to be immunochemically identical to porcine zona antigens by crossed‐line immunoelectrophoresis.
