Recombinant Rat Interleukin-10 (rRtIL-10)

• Catalog Number: orb1494999
• Category: Proteins
• Description: Interleukin-10 also known as cytokine synthesis inhibitory factor (CSIF), is coded by IL10 gene on chromosome 13 in rat. the charter member of the IL 10 family of α helical cytokines that also includes IL19, IL20, IL22, and IL24 (1, 2). IL10 is secreted by many activated hematopoietic cell types as well as hepatic stellate cells, keratinocytes. IL-10 inhibits the expression of proinflammatory cytokines such as IL-1 and TNFα. Like IL-4, IL-10 enhances humoral immune responses and attenuates cell-mediated immune reactions. Human IL-10 active on murine cells, but murine IL-10 is inactive on human cells.
• Form/Appearance: Lyophilized from a 0.2mm filtered concentrated solution in PBS, pH 7.4.
• Purity: > 97% by SDS-PAGE and HPLC analyses.
• MW: Approximately 18.6 kDa, a single non-glycosylated polypeptide chain containing 160 amino acid residues.
• Protein Sequence: SKGHSIKGDN NCTHFPVSQT HMLRELRAAF SQVKTFFQKK DQLDNIVLTD SLLQDFKGYL GCQALSEMIK FYLVEVMPQA ENHGPEIKEH LNSLGEKLKT LWIQLRRCHR FLPCENKSKA VEQVKNDFNK LQDKGVYKAM NEFDIFINCI EAYVTLKMKN
• Source: Escherichia coli.
• Biological Activity: Measured in a cell proliferation assay using MC/92 mouse mast cells. The ED50 for this effect is typically 2-12ng/mL.
• Endotoxins: Less than 1EU/μg of rRtIL-10 as determined by LAL method.
• 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.
• Buffer/Preservatives: Lyophilized from a 0.2mm filtered concentrated solution in PBS, pH 7.4.
• 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. 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 < -20°C. Further dilutions should be made in appropriate buffered solutions.
• Expiration Date: 6 months from date of receipt.
