Alternative Name(s): Alpha-2,8-sialyltransferase 8DPolysialyltransferase-1Sialyltransferase 8D ;SIAT8-DSialyltransferase St8Sia IV ;ST8SiaIV
Relevance: Catalyzes the polycondensation of alpha-2,8-linked sialic acid required for the synthesis of polysialic acid (PSA), which is present on the bryonic neural cell adhesion molecule (N-CAM), necessary for plasticity of neural cells.
Reference: Expression cloning of a human polysialyltransferase that forms the polysialylated neural cell adhesion molecule present in embryonic brain.Nakayama J., Fukuda M.N., Fredette B., Ranscht B., Fukuda M.Proc. Natl. Acad. Sci. U.S.A. 92:7031-7035(1995)
Purity: Greater than 90% as determined by SDS-PAGE.
Storage Buffer: Tris-based buffer，50% glycerol
Storage: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20℃/-80℃. The shelf life of lyophilized form is 12 months at -20℃/-80℃.
Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.
