• Formulation Tris-based buffer50% 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˚C,-80˚C. The shelf life of lyophilized form is 12 months at -20˚C,-80˚C.
  Notes:Repeated freezing and thawing is not recommended. Store working aliquots at 4˚C for up to one week.

Plays a central role in the biogenesis of melanosomes. Involved in the maturation of melanosomes from stage I to II. The transition from stage I melanosomes to stage II melanosomes involves an elongation of the vesicle, and the appearance within of distinct fibrillar structures. Release of the soluble form, ME20-S, could protect tumor cells from antibody mediated immunity.

A melanocyte-specific gene, Pmel 17, maps near the silver coat color locus on mouse chromosome 10 and is in a syntenic region on human chromosome 12.Kwon B.S., Chintamaneni C., Kozak C.A., Copeland N.G., Gilbert D.J., Jenkins N.A., Barton D., Francke U., Kobayashi Y., Kim K.-K.Proc.
