Purity: >97% by SDS-PAGE and HPLC analyses.
Biological Activity: Fully biologically active when compared to standard. The ED50 determined by a cell proliferation
assay using murine MC/9-2 cells is less than 12 ng/ml, corresponding to a specific activity of> 8.3
× 104 IU/mg.
Physical Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation: Lyophilized from a 0.2μm filtered concentrated solution in PBS, pH 7.4.
Endotoxin: Less than 1EU/μg of rRtIL-10 as determined by LAL method.
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 apportioned into working aliquots and
stored at <-20°C. Further dilutions should be made in appropriate buffered solutions.
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.
Usage: This material is offered by Shanghai Corning Bio-Tech for research, laboratory or further
evaluation purposes. NOT FOR HUMAN USE.
Rat Interleukin-10
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.
