Luetcke H.A., Rausch U., Vasiloudes P., Scheele G.A., Kern H.F. Nucleic Acids Res. 17:6736-6736(1989)Purity: Greater than 85% as determined by SDS-PAGE.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.
