• Application notes: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
• Endotoxins: ≤10 EU/mg by the LAL method
• Source: Mammalian cell
• Biological Origin: Homo sapiens (Human)
• Biological Activity: Measured in a cell proliferation assay using MCF-7 breast cancer cell line. The ED50 for this effect is 1-8 ng/mL.
• Expression Region: 20-242aa
• 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.
