产品英文概述

Interleukin-10 (IL-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.

来源

Escherichia coli.

分子量

Approximately 18.6 kDa, a single non-glycosylated polypeptide chain containing 160 amino acids.

生物活性

Fully biologically active when compared to standard. The ED50 as determined by a cell proliferation assay using murine MC/9-2 cells is less than 1 ng/ml, corresponding to a specific activity of > 1.0 × 106 U/mg.

外观

Sterile filtered white lyophilized (freeze-dried) powder.

配方

Lyophilized from a 0.2 um filtered concentrated solution in PBS, pH 6.0, with 0.02 % Tween-20.

内毒素

Less than 0.01 EU/ug of rHuIL-10 GMP as determined by LAL method.

溶解说明

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.

储存条件

Use a manual defrost freezer and avoid repeated freeze-thaw cycles.- A minimum of 12 months when stored at ≤ -20 °C as supplied. Refer to lot specific COA for the Use by Date.- 1 month, 2 to 8 °C under sterile conditions after reconstitution.- 3 months, -20 to -70 °C under sterile conditions after reconstitution.
