• Protein Length: Full Length of Mature Protein
• Source: E.Coli
• Biological Origin: Mus musculus (Mouse)
• Biological Activity: Fully biologically active when compared to standard. The ED50 as determined by a cell proliferation assay using human N1186 T cells is less than 25 ng/ml, corresponding to a specific activity of ＞ 4.0 × 104 IU/mg.
• Expression Region: 18-146aa
• Endotoxins: Less than 1.0 EU/µg as determined by LAL method.
• 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℃.
• Buffer/Preservatives: Lyophilized from a 0.2 μm filtered 2 × PBS, pH 7.4
• Alternative names: IL-21,
• Background: Cytokine with immunoregulatory activity. May promote the transition between innate and adaptive immunity. Induces the production of IgG(1) and IgG(3) in B-cells. May play a role in proliferation and maturation of natural killer (NK) cells in synergy with IL15. May regulate proliferation of mature B- and T-cells in response to activating stimuli. In synergy with IL15 and IL18 stimulates interferon gamma production in T-cells and NK cells (By similarity). During T-cell mediated immune response may inhibit dendritic cells (DC) activation and maturation. {ECO:0000250, ECO:0000269|PubMed:11970879, ECO:0000269|PubMed:12893770, ECO:0000269|PubMed:15100251}.
• Note: For research use only
• 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.
