蛋白结构(Molecular Characterization)
This protein carries no "tag".
The protein has a calculated MW of 55.0 kDa. The protein migrates as 58 kDa±3 kDa under reducing (R) condition, and 58 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under non-reducing (NR) condition (SDS-PAGE) due to glycosylation.
内毒素(Endotoxin)
Less than 0.1 EU per μg by the LAL method / rFC method.
无菌(Sterility)
Negative
支原体(Mycoplasma)
Negative
纯度(Purity)
>95% 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-23亚基α(IL-23 alpha)可与IL12B结合形成IL-23白细胞介素,这是一种在先天性与适应性免疫中发挥作用的异二聚体细胞因子。IL-23可能与IL-17共同构成外周组织对感染的急性应答机制。IL-23通过与由IL12RB1和IL23R组成的异二聚体受体复合物结合,激活Jak-Stat信号传导级联反应,刺激记忆T细胞(而非初始T细胞)并促进促炎细胞因子的产生。IL-23会诱导自身免疫性炎症,因此可能是自身免疫性炎症疾病的致病因子,并在肿瘤发生过程中发挥重要作用。
