• Protein Length: Full Length of Mature Protein
• UniProt ID: P60568
• MW: 41.5 kDa
• 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: Less than 1.0 EU/ug as determined by LAL method.
• Source: Mammalian cell
• Biological Origin: Homo sapiens (Human)
• Biological Activity: Measured by its binding ability in a functional ELISA. Immobilized Human IL2RA at 2 μg/mL can bind Human IL2 , the EC50 is 0.4992 to 0.6269 ng/mL.
• Expression Region: 21-153aa
• 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.
• Alternative names: IL-2;T-cell growth factor (TCGF);Aldesleukin
