Abstract

The cleidoic egg-case of the dogfish appears to have a highly porous and permeable outer membrane, the pore radius being computed to be 13.6 A. It does not present any physiological barrier to small molecules and therefore constitutes an open ionic and osmotic system for the embryo. Being a porous protein membrane it may be of value as a model for molecular transport mechanisms.

摘要

角鲨的有壳卵似乎有一层高度多孔且可渗透的外膜，计算得出的孔径半径为13.6埃。它对小分子不存在任何生理屏障，因此对胚胎而言构成了一个开放的离子和渗透系统。作为一种多孔蛋白质膜，它可能作为分子运输机制的模型具有价值。
