Murine Interleukin-10 (rMuIL-10)

• Catalog Number: orb1495011
• Category: Proteins
• Description: IL-10 is an immunosuppressive cytokine produced by a variety of mammalian cell types including macrophages, monocytes, T cells, B cells and 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: Sterile Filtered White lyophilized (freeze-dried) powder.
• MW: Approximately 18.7 kDa, a single non-glycosylated polypeptide chain containing 161 amino acids
• Protein Sequence: MSRGQYSRED NNCTHFPVGQ SHMLLELRTA FSQVKTFFQT KDQLDNILLT DSLMQDFKGY LGCQALSEMI QFYLVEVMPQ AEKHGPEIKE HLNSLGQKLK TLRMRLRRCH RFLPCENKSK AVEQVKSDFN KLEDQGVYKA MNEFDIFINC IEAYMMIKMK S
• Source: Escherichia coli.
• Biological Activity: Fully biologically active when compared to standard. The ED50 as determined by the dose-dependent co-stimulation (with IL-4) of the proliferation of murine MC/9 cells was found to be 5 x 105 units/mg.
• Endotoxins: Less than 1EU/mg of rMuIL-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.
