Cynomolgus IL-31 Protein, His Tag
分子别名(Synonym)
IL-31, IL31, Interleukin-31
表达区间及表达系统(Source)
Cynomolgus IL-31, His Tag (IL1-C5245) is expressed from human 293 cells (HEK293). It contains AA Leu 27 - Thr 163 (Accession # G7PJ78-1).
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 17.3 kDa. The protein migrates as 20-25 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
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
IL-31是一种炎症性细胞因子,能协助启动针对病原体的细胞免疫应答。它通过由IL31RA和OSMR组成的IL-31异二聚体受体,激活STAT3信号通路,并可能激活STAT1与STAT5。该细胞因子已被确认为多种慢性炎症性疾病(包括特应性皮炎)的关键致病因子,可能在皮肤免疫中发挥功能。IL-31由多种细胞产生,主要为2型辅助性T细胞(TH2)。IL-31通过免疫细胞和上皮细胞中表达的IL-31RA与抑瘤素M受体β(OSMRβ)构成的受体复合物传递信号,这些信号会激活三条通路:ERK1/2 MAP激酶通路、PI3K/AKT通路以及JAK1/2信号通路。
