蛋白结构(Molecular Characterization)

This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 18.5 kDa. The protein migrates as 35-45 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.
>90% as determined by SEC-MALS.
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18结合蛋白(IL18BP)亦称为Tadekinig-alfa、IL18BPa,其功能为IL18抑制剂。该蛋白是一种分泌型蛋白,包含一个免疫球蛋白样C2型结构域。由于缺乏跨膜结构域,IL18BP不会锚定在细胞膜上。其在心脏、肺、胎盘和脾脏中呈现高表达。IL18BP的A亚型可与IL-18结合并抑制其活性,还能作为早期TH1细胞因子反应的抑制剂。该蛋白通过抑制γ干扰素(IFN-γ)的产生,进而削弱1型辅助T细胞(Th1)的免疫应答。
