表達區(qū)間及表達系統(tǒng)(Source)
Mouse IL-33, His Tag (IL3-M5245) is expressed from human 293 cells (HEK293). It contains AA Ser 109 - Ile 266 (Accession # Q8BVZ5-1).
蛋白結構(Molecular Characterization)
This protein carries a polyhistidine tag at the N-terminus.
The protein has a calculated MW of 19.5 kDa. The protein migrates as 20-30 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
內(nèi)毒素(Endotoxin)
Less than 1.0 EU per μg by the LAL method.
純度(Purity)
>90% as determined by SDS-PAGE.
制劑(Formulation)
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

背景(Background)
白細胞介素33(IL33)被稱為C9orf26、DKFZp586H0523、DVS27、NF-HEV、NFEHEV、RP11-575C20.2,是一種屬于IL-1超家族的細胞因子。IL-33誘導輔助性T細胞、肥大細胞、嗜酸性粒細胞和嗜堿性粒細胞產(chǎn)生2型細胞因子。IL-33通過與受體ST2(又名IL1RL1)和IL-1受體輔助蛋白(IL1RAP)相互作用,激活NF-κB和MAP激酶信號通路中的細胞內(nèi)分子,驅(qū)動極化Th2細胞產(chǎn)生2型細胞因子(如IL-5和IL-13),從而介導其生物學效應。在體內(nèi),IL-33誘導IL-4、IL-5和IL-13的表達,并導致粘膜器官的嚴重病理變化。
