Human IL-22 Protein, His Tag

分子别名(Synonym)

IL-22,IL-TIF,ZCYTO18

表达区间及表达系统(Source)

Human IL-22, His Tag (IL2-H524a) is expressed from human 293 cells (HEK293). It contains AA Ala 34 - Ile 179 (Accession # Q9GZX6-1).

Predicted N-terminus: His

蛋白结构(Molecular Characterization)

Unconjugated(Ala 34 - Ile 179) Q9GZX6-1

This protein carries a polyhistidine tag at the N-terminus.

The protein has a calculated MW of 18.6 kDa. The protein migrates as 28-34 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

内毒素(Endotoxin)

Less than 1.0 EU per μg by the LAL method.

纯度(Purity)

>90% as determined by SDS-PAGE.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

背景(Background)

Interleukin-22 (IL22) is also known as cytokine Zcyto18, IL-10-related T-cell-derived-inducible factor (IL-TIF), which is belongs to the IL-10 family or IL-10 superfamily (including IL-19, IL-20, IL-24, and IL-26), a class of potent mediators of cellular inflammatory responses. IL-22 is produced by activated DC and T cells and initiates innate immune responses against bacterial pathogens especially in epithelial cells such as respiratory and gut epithelial cells. IL-22 biological activity is initiated by binding to a cell-surface complex composed of IL-22R1 and IL-10R2 receptor chains and further regulated by interactions with a soluble binding protein IL-22BP. IL-22 also promotes hepatocyte survival in the liver and epithelial cells in the lung and gut similar to IL-10.
