title: Effect of varying glycerol and sucrose concentration combinations on embryo survival rate in a one-step cryoprotectant removal from frozen-thawed ovine embryos.
abstract: Two hundred fifty-one ovine embryos were frozen in different levels of glycerol (1.0, 1.4, 2.0 or 2.8M) and thawed into one of four sucrose levels (0, 0.25, 1.0 or 2.0M) to determine the optimal glycerol-sucrose combination for one-step, in-straw thawing. Sucrose was toxic at low glycerol levels and mandatory at high levels. The 1.0M sucrose level with either 1.4 or 2.0M glycerol was optimal for one-step cryoprotectant removal.
