EpCAM is also known as CO171A, EGP, EGP40,GA7332, KSA, M4S, MIC18, MK1, TROP1, hEGP2, and is a pan-epithelial differentiation antigen that is expressed on almost all carcinomas as 17-1A(mAb) antigen. Its constitutional function is being elucidated. It is intricately linked with the Cadherin-Catenin pathway and hence the fundamental WNT pathway responsible for intracellular signaling and polarity. The epithelial cell adhesion molecule (Ep-CAM) is known to express in most epithelial malignancies and was reported as a tumor marker or a candidate of molecular targeting therapy. Ep-CAM cross signaling with N-cadherin involves Pi3K, resulting in the abrogation of the cadherin adhesion complexes in epithelial cells was reported. And Epithelial cell adhesion molecule (Ep-CAM) recently received increased attention as a prognostic factor in breast cancer.

Recombinant MABSol® Biotinylated Human EpCAM, His Tag, primary amine labeling (EPM-H8223) is expressed from human HEK293 cells. It contains AA Gln 24 - Lys 265 (Accession # AAH14785.1). It is the biotinylated form of Human EpCAM, His Tag (EPM-H5223).
Predicted N-terminus: Gln 24


Molecular Characterization
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 28.2 kDa. The protein migrates as 33-36 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

The primary amines in the side chains of lysine residues and the N-terminus of the protein are conjugated with biotins using standard chemical labeling method. A standard biotin reagent (13.5 angstroms) is used in this product.

Biotin:Protein Ratio
The biotin to protein ratio is 3-5 as determined by the HABA assay.

Less than 1.0 EU per μg by the LAL method.

>95% as determined by SDS-PAGE.

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization..
