产品描述:
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.

表达系统 :
Escherichia coli

溶解方法:
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.

产品组成:
Lyophilized from a 0.2 μm filtered concentrated solution in PBS, pH 7.4.

存储条件:
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.

分子量:
Approximately 18.6 kDa, a single non-glycosylated polypeptide chain containing 160 amino acid residues.

内毒素:
Less than 1 EU/μg of IL-10 as determined by LAL method.

产品用途:
This material is offered by Cyagen Biosciences for research, laboratory or further evaluation purposes. FOR RESEARCH USE ONLY. NOT INTENDED FOR ANY ANIMAL OR HUMAN THERAP EUTIC OR DIAGNOSTIC USE.

生物学活性:
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.

产品形态:
