Vitrification of turbot embryos: preliminary assays.

abstract：:We have shown previously that the survival of human red blood cells during slow freezing at 2% hematocrit is dependent more on the magnitude of the unfrozen fraction than on the salt concentration in that unfrozen fraction. In parallel, first Nei and more recently Pegg and colleagues have shown that survival is affect...
