Purity

>95% by SDS-PAGE and HPLC analyses.

Biological Activity

Fully biologically active when compared to standard. The ED50 as determined by inducing IL-8 secretion of human HepG2 cells is less than 1.0μg/ml, corresponding to a specific activity of >1000IU/mg.

Physical Appearance

Sterile Filtered lyophilized (freeze-dried) liquid-like powder.

Formulation

Lyophilized from a 0.2μm filtered concentrated solution in PBS, pH7.4, with 0.1% Tween-20 and 3% Trehalose.

Endotoxin

Less than 0.1EU/μg of rHuIL-17B 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 0.1-1.0mg/ml. Stock solutions should be apportioned into working aliquots and stored at ≤-20℃. Further dilutions should be made in appropriate buffered solutions.

Background

IL-17B, also named IL20, NIRF and ZCYTO7, is belonging to the IL-17 family and it stimulates the release of tumor necrosis factor alpha and IL-1-beta from the monocytic cell line THP-1. IL-17B mRNA is expressed in adult pancreas, small intestine, and stomach. The IL-17 family is comprised of at least six proinflammatory cytokines that share a conserved cysteine-knot structure but diverge at the N-terminus. IL-17 family members are glycoproteins secreted as dimers that induce local cytokine production and recruit granulocytes to sites of inflammation. IL-17B binds the IL-17B receptor, but not the IL-17 receptor; it is most homologous with IL-17D, which is expressed by resting CD4⁺ T cells and CD19⁺ B cells. This cytokine was reported to stimulate the release of TNF alpha (TNF) and IL1 beta (IL1B) from a monocytic cell line. Immunohistochemical analysis of several nerve tissues indicated that this cytokine is primarily localized to neuronal cell bodies.
