Preparation and Storage
Stability and Storage
Shipped at 4°C. Upon delivery aliquot and store at -20°C or -80°C. Avoid repeated freeze / thaw cycles.
This product is an active protein and may elicit a biological response in vivo, handle with caution.
Reconstitute in sterile 18MOhm/cm H2O to not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
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.
Expressed in activated CD4-positive T-cells but not in CD8-positive T-cells, B-cells, or monocytes.
