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 apportioned into working aliquots and stored at \u0026lt;-20°C. Further dilutions should be made in appropriate buffered solutions.\u003c\/p\u003e\n\n\u003cp\u003eStorage: 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.\u003c\/p\u003e\n\n\u003cp\u003eUsage: This material is offered by USA Bioworld biotech for research, laboratory or further evaluation purposes. NOT FOR HUMAN USE. Made in China\u003c\/p\u003e\n\n\u003cp\u003eDescription: Interleukin 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.\u003c\/p\u003e","brand":"BioWorld","offers":[{"title":"2µg","offer_id":42882216067251,"sku":"PR1057-2","price":260.23,"currency_code":"CAD","in_stock":true},{"title":"10µg","offer_id":42882216100019,"sku":"PR1057-10","price":490.83,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0305\/9482\/6376\/products\/thumbnail_d1447bac803ec9be_11-14-09-19-51_07636c25-75fc-4d78-9b19-0e9985fb5851.jpg?v=1702049460","url":"https:\/\/afsbio.com\/products\/recombinant-human-interleukin-10-rhuil-10-pr1057","provider":"AFSBio Inc.","version":"1.0","type":"link"}
