Predicted N-terminus: His
重組人IL-33蛋白,His Tag,premium級(jí)(IL3-H52H7),專為臨床前階段設(shè)計(jì),具有與GMP級(jí)重組人IL-33蛋白相同的活性和性能,可實(shí)現(xiàn)從臨床前開發(fā)到臨床階段的無縫過渡。在原材料安全不是首要任務(wù)的早期開發(fā)階段,premium產(chǎn)品為GMP級(jí)產(chǎn)品提供了一種經(jīng)濟(jì)高效的替代品。通過在早期開發(fā)階段使用Premium Grade產(chǎn)品,您可以輕松過渡到臨床和商業(yè)階段,而無需重新驗(yàn)證原材料和修改制造工藝。
蛋白結(jié)構(gòu)(Molecular Characterization)
This protein carries a polyhistidine tag at the N-terminus.
The protein has a calculated MW of 20.2 kDa. The protein migrates as 25-30 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
內(nèi)毒素(Endotoxin)
Less than 0.1 EU per μg by the LAL method.
無菌(Sterility)
Negative
支原體(Mycoplasma)
Negative.
純度(Purity)
>95% as determined by SDS-PAGE.
制劑(Formulation)
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

背景(Background)
白細(xì)胞介素33(IL-33)被稱為C9orf26、DKFZp586H0523、DVS27、NF-HEV、NFEHEV、RP11-575C20.2,是一種屬于IL-1超家族的細(xì)胞因子。IL-33誘導(dǎo)輔助性T細(xì)胞、肥大細(xì)胞、嗜酸性粒細(xì)胞和嗜堿性粒細(xì)胞產(chǎn)生2型細(xì)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(hào)通路中的細(xì)胞內(nèi)分子,驅(qū)動(dòng)極化Th2細(xì)胞產(chǎn)生2型細(xì)胞因子(如IL-5和IL-13),從而介導(dǎo)其生物學(xué)效應(yīng)。在體內(nèi),IL-33誘導(dǎo)IL-4、IL-5和IL-13的表達(dá),并導(dǎo)致粘膜器官的嚴(yán)重病理變化。
