title: Large scale isolation of zonae pellucidae from ovarian oocytes of mice.
abstract: A large scale method for the isolation of zonae pellucidae (ZP) from mouse ovaries is described. It involves the squashing of the ovaries on a screen (70 X 70 M mesh) and sedimentation of the material in a discontinuous gradient. It is possible to obtain free ZP in useful quantities in about 1 h's work.
