表达区间及表达系统(Source)
Human EpCAM, Fc Tag (EPM-H5254) is expressed from human 293 cells (HEK293). It contains AA Gln 24 - Lys 265 (Accession # AAH14785.1).
Predicted N-terminus: Gln 24
蛋白结构(Molecular Characterization)

This protein carries a human IgG1 Fc tag at the C-terminus.
The protein has a calculated MW of 53.5 kDa. The protein migrates as 60-65 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
内毒素(Endotoxin)
Less than 0.2 EU per μg by the LAL method / rFC method.
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
上皮细胞粘附分子(EpCAM)也被称为CO171A、EGP、EGP40、GA7332、KSA、M4S1、MIC18、MK1、TROP1、hEGP2。它是一种全上皮分化抗原,在几乎所有上皮源性癌中作为17-1A(单克隆抗体)抗原表达。其基本生理功能正在被阐明。EpCAM与钙粘蛋白-连环蛋白通路密切相关,进而与负责细胞内信号传导和极性的核心WNT通路相关联。已知上皮细胞粘附分子在大多数上皮来源恶性肿瘤中表达,并被报道为一种肿瘤标志物或分子靶向治疗的候选靶点。
据报道,Ep-CAM与N-钙粘蛋白的交叉信号传导涉及Pi3K通路,导致上皮细胞中钙粘蛋白粘附复合物的功能丧失。此外,上皮细胞粘附分子近期作为乳腺癌的预后因素受到了越来越多的关注。
