重組人IL-33蛋白,His Tag,premium級(IL3-H52H7),專為臨床前階段設計,具有與GMP級重組人IL-33蛋白相同的活性和性能,可實現(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的早期開發(fā)階段,premium產品為GMP級產品提供了一種經(jīng)濟高效的替代品。通過在早期開發(fā)階段使用Premium Grade產品,您可以輕松過渡到臨床和商業(yè)階段,而無需重新驗證原材料和修改制造工藝。
蛋白結構(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分子,驅動極化Th2細胞產生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,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。
