表达区间及表达系统(Source)
Biotinylated Human EpCAM, Avitag,His Tag (EPM-H82E8) 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 an Avi tag (Avitag™) at the C-terminus, followed by a polyhistidine tag.
The protein has a calculated MW of 30.0 kDa. The protein migrates as 34-45 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
标记(Labeling)
Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
蛋白标记度(Protein Ratio)
Passed as determined by the HABA assay / binding ELISA.
内毒素(Endotoxin)
Less than 0.1 EU per μg by the LAL method / rFC method.
纯度(Purity)
>95% 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
上皮细胞黏附分子(EpCAM)亦称CO171A、EGP、EGP40、GA7332、KSA、M4S1、MIC18、MK1、TROP1、hEGP2,是一种泛上皮分化抗原,可作为17-1A(单克隆抗体)抗原在几乎所有上皮源性癌组织中表达。其生理功能正在被逐步阐明:该分子与钙黏蛋白-连环蛋白通路存在复杂关联,进而影响负责细胞内信号传导与极性建立的核心WNT通路。研究显示,上皮细胞黏附分子(Ep-CAM)在大多数上皮源性恶性肿瘤中均有表达,已被确认为肿瘤标志物及分子靶向治疗的候选靶点。
有研究表明,Ep-CAM与N-钙黏蛋白通过Pi3K介导交叉信号传导,这一过程会导致上皮细胞中钙黏蛋白黏附复合物的功能丧失。近年来,上皮细胞黏附分子(Ep-CAM)作为乳腺癌预后评估因子受到越来越多关注。
