Beta-hemolysin is a phospholipase C with specific activity toward sphingomyelins. Has a high specificity for sphingomyelin, hydrolyzes lysophosphatidylcholine at a much lower rate, but has no activity towards phosphatidylcholine, phosphatidylethanolamine, or phosphatidylserineReference: "Insertional inactivation of the Staphylococcus aureus beta-toxin by bacteriophage phi 13 occurs by site- and orientation-specific integration of the phi 13 genome." Coleman D., Knights J., Russell R., Shanley D., Birkbeck T.H., Dougan G., Charles I. Mol. Microbiol. 5:933-939(1991)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.
