表达区间及表达系统(Source)
Cynomolgus IL-13, His Tag (IL3-C5249) is expressed from human 293 cells (HEK293). It contains AA Ser 21 - Asn 132 (Accession # ABG75889.1).
Predicted N-terminus: His
蛋白结构(Molecular Characterization)

This protein carries a polyhistidine tag at the N-terminus.
The protein has a calculated MW of 14.2 kDa. The protein migrates as 25-39 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
内毒素(Endotoxin)
Less than 1.0 EU per μg by the LAL method / rFC method.
纯度(Purity)
>90% as determined by SDS-PAGE.
制剂(Formulation)
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

背景介绍
白细胞介素13(IL-13)亦称ALRH、BHR1或P600,是一种单链糖基化多肽,作为调控炎症和免疫应答的关键细胞因子。该因子由多种细胞分泌,尤其以2型辅助T细胞(Th2)为主要来源。
IL-13通过多亚基受体发挥作用,该受体包含IL-4受体α链(IL-4Rα)及至少一条已知的IL-13特异性结合链。虽然IL-13的功能与IL-4存在显著重叠(特别是在造血细胞诱导的变化方面),但由于IL-4作用更强效,这些重叠功能的生物学意义相对次要。
IL-13可诱导基质金属蛋白酶(MMPs)的产生,这种保护机制能防止导致窒息风险的过度过敏性炎症。该细胞因子会引发过敏性肺病的多项特征性病变:包括气道高反应性、杯状细胞化生及黏液过度分泌,这些病理改变共同导致气道阻塞。
