Biological Activity: Fully biologically active when compared to standard. The ED50 as determined by by a cell proliferation assay using human N1186 T cells is less than 20 ng/ml, corresponding to a specific activity of > 5.0 × 104 IU/mg.

MW: 15.4 kDa

Purity: >97% as determined by SDS-PAGE and HPLC.

Endotoxin: Less than 1.0 EU/µg as determined by LAL method.

Relevance: 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 (By similarity) . 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. During T-cell mediated immune response may inhibit dendritic cells (DC) activation and maturation. {ECO:0000250, ECO:0000269|PubMed:11081504, ECO:0000269|PubMed:15178704}.

Tissue Specificity: Expressed in activated CD4-positive T-cells but not in CD8-positive T-cells, B-cells, or monocytes.

Paythway: Jak-STATsignalingpathway

Form: Lyophilized powder

Buffer: Lyophilized from a 0.2 µm filtered PBS, pH 7.4

Reconstitution: 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.
