IL18BP (Interleukin-18-binding Protein, IL-18BP, Tadekinig-alfa)
Description:
IL-18BP, a 40kD glycoprotein, is a member of Ig super family. It consists of a single Ig-like domain and acts as a circulating anti-inflammatory protein. It is a secretory protein which binds to IL-18 with high affinity and prevents its interaction with IL-18R, resulting in inhibition of IL-18 induced IFN-gamma, IL-8 and NF-kB production. Its expression is up-regulated by IFN-gamma, thus providing a negative feed-back mechanism in shutting off IL-18 mediated immune responses. It is constitutively expressed in mononuclear cells and its role has been implicated in treatment of contact hypersensitivity. Northern Blot analysis detected a strong expression in spleen and its pathological implications have been observed in Crohn's disease.

Applications:
Suitable for use in Western Blot. Other applications not tested.

Recommended Dilution:
Western Blot: 1:500-1:1000
