Introduction
Interleukin-18 Binding Protein (IL18BP) serves as an inhibitor of the proinflammatory cytokine, IL18. IL18BP binds IL18, inhibits the binding of IL18 to its receptor, and consequently inhibits IL18-induced IFN-gamma production, resulting in reduced T-helper type 1 immune responses. The IL18BP protein is constitutively expressed and secreted in mononuclear cells. Elevated levels of IL18BP protein are detected in the intestinal tissues of patients with Crohn's disease.
Description
IL18BP Human Recombinant produced in Sf9 Baculovirus
cells is a single, non-glycosylated polypeptide chain containing 406 amino acids
(31-194a.a) and having a molecular mass of 44.9kDa. (Molecular size on SDS-PAGE
will appear at approximately 40-57kDa).
IL18BP is fused to a 239 amino acid hIgG-His-tag at C-terminus
& purified by proprietary chromatographic techniques.
Source
Sf9, Baculovirus cells.
Physical Appearance
Sterile filtered colorless solution.
