Description
Trehalose is a non-reducing disaccharide, ubiquitously present in nature. It is used as a food preservative and also to retain enzymes, vaccines, cells and many other molecules. Trehalose is present as hemolymph sugar among the invertebrates.D-(+)-Trehalose dihydrate has been used in a slow-freezing method for freezing rabbit oocytes. It has also been used in solid-surface vitrification (SSV) of in vitro-matured oocytes. It is suitable for use as a cryoprotectant in a variety of cell freezing media
