Influence of lipids on ice formation in cryoprotective media

Abstract

Cryomicroscopic analysis demonstrated that two lipid preparations from marine vertebrates (<0.1%) and liposomes prepared from rainbow trout sperm lipids (<0.5%) efficiently hindered the growth of ice crystals during freezing of multicomponent cryoprotective media used for trout sperm cryopreservation. At higher lipid concentrations, crystals either did not form at all or had altered shape and blurred boundaries. Addition of egg yolk (10%) together with these lipids increased the size of crystal structures and markedly changed their shape.
