Many broadcast-spawning species have therefore evolved a block to polyspermy that involves the rapid reversal of the electrical potential of the egg membrane after the penetration of a sperm and thus prevents further entry of sperm (Metz et al.
Because of the more rapid development and shorter duration time, the presence of stage I embryos, which are enveloped in an egg membrane, was less often observed.
To alter the amount of DAG in unfertilized or fertilized egg membranes, we microinjected enzymes that would lower DAG either by converting it to phosphatidic acid or by depleting the major precursor of DAG,[ PIP.
The vitelline layer covers the egg membrane, which is formed into a series of microvilli.
Early development occurs within the egg membrane and the veliger larval stage is reached approximately three days after fertilization.
When the scientists applied the viral toxin to both sides of the egg membrane to mimic the killer-yeast cells' situation, the potassium channels stayed shut most of the time.
HEM[TM] Hydrolysate--Hydrolyzed Egg Membrane (patent pending)
Fluid convection on either side of the egg membrane would allow for greater oxygen extraction from the environment by eliminating boundary layers and maintaining a diffusional gradient.
Because this method bypasses the normal zona-closing mechanism, it sometimes allows more than one sperm to penetrate the egg membrane, creating a "polyspermic" egg that can't develop properly and must be discarded.
Alternatively, they may be protected from changes in external conditions by the perivitelline fluid, the fluid inside the inner egg membrane, which may buffer embryos from changes in external conditions, especially salinity.
Biova LLC, Johnston, IA, a supplier of water-soluble egg membrane, has finalized an agreement with Maypro Industries, Purchase, NY, which will be the preferred distributor of Biova's ingredient portfolio in Japan and Taiwan.
castaneus, from which the jelly coat and part of the vitelline layer have been stripped to reveal a honeycomb of egg membrane cups.
Biova is a market leader for water-soluble egg membrane ingredients, "increased market interest in our water-soluble branded ingredients and expanded global opportunities are the driving forces behind this agreement," said Matt Stegenga, Biova director of sales and marketing.
Once the sperm have penetrated the vitelline layer, the long nuclear filament bridges the gap to cups in the egg membrane.
