Product Description

Human IL-33 is a proinflammatory protein that shares structural and functional characteristics with the IL-1 cytokine family. It binds and signals through the IL-1RL1/ST2 receptor activating NF-kappaB and MAP kinases. IL-33 induces production of TH2 cell related cytokines, including IL-4, IL-5 and IL-13, and exerts multiple inflammation related bioactivities. Recombinant human IL-33 is a 17.9kD protein containing 159aa. Source: Recombinant protein corresponding to human IL-33, expressed in E.coli. Biological Activity: Determined by the dose-dependent stimulation of the proliferation of murine D10S cells. The ED50 was found to be 0.05ng/ml Specific Activity: 2x10e7units/mg Endotoxin: <0.1ng/ug (1EU/ug) AA Sequence: MSITGISPIT EYLASLSTYN DQSITFALED ESYEIYVEDL KKDEKKDKVL LSYYESQHPS NESGDGVDGK MLMVTLSPTK DFWLHANNKE HSVELHKCEK PLPDQAFFVL HNMHSNCVSF ECKTDPGVFI GVKDNHLALI KVDSSENLCT ENILFKLSET Storage and Stability: May be stored at 4C for short-term only.
