• Formulation Lyophilized from a 0.2 μm filtered concentrated solution in PBS, pH 7.4.
• Reconstitution We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1 % BSA to a concentration of 0.1-1.0 mg mL. Stock solutions should be apportio
• Storage This lyophilized preparation is stable at 2-8 ˚C, but should be kept at -20 ˚C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8 ˚C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20 ˚C to -70 ˚C. Avoid repeated freeze thaw cycles.

Interleukin-10 (IL-10), also known as cytokine synthesis inhibitory factor (CSIF), is the charter member of the IL-10 family of α-helical cytokines that also includes IL-19, IL-20, IL-22, IL-24, and IL-26 AK155. IL-10 is secreted by many activated hematopoietic cell types as well as hepatic stellate cells, keratinocytes, and placental cytotrophoblasts. Whereas human IL-10 is active on mouse cells, mouse IL-10 does not act on human cells. IL-10 is a 178 amino acid molecule that contains two intrachain disulfide bridges and is expressed as a 36 kDa noncovalently associated homodimer. The IL-10 dimer binds to two IL-10 Rα IL-10R1 chains, resulting in recruitment of two IL-10 Rβ IL-10R2 chains and activation of a signaling cascade involving JAK1, TYK2, and STAT3. IL-10Rβ does not bind IL-10 by itself but is required for signal transduction. IL-10 is a critical molecule in the control of viral infections and allergic and autoimmune inflammation. It promotes phagocytic uptake and Th2 responses but suppresses antigen presentation and Th1 proinflammatory responses.
