表达区间及表达系统(Source)

MABSol® Biotinylated Human EpCAM / TROP1 (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 / TROP1 Protein (Cat # EPM-H5223).

Predicted N-terminus: Gln 24

蛋白结构(Molecular Characterization)

Online(Gln 24 - Lys 265) AAH14785.1

This protein carries a polyhistidine tag at the C-terminus. The protein has a calculated MW of 29 kDa. The protein migrates as 33-36 kDa on a SDS-PAGE gel under reducing (R) condition due to glycosylation.

标记(Biotinylation)

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.

蛋白标记度(Biotin:Protein Ratio)

The biotin to protein ratio is 6-7 as determined by the HABA assay.

内毒素(Endotoxin)

Less than 1.0 EU per μg by the LAL method.

纯度(Purity)

>95% as determined by reduced SDS-PAGE.

制剂(Formulation)

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

重构方法(Reconstitution)

Please see Certificate of Analysis for specific instructions.

For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.

存储(Storage)

For long term storage, the product should be stored at lyophilized state at -20°C or lower.

Please avoid repeated freeze-thaw cycles.

No activity loss was observed after storage at:

  1. 4-8°C for 12 months in lyophilized state;
  2. -70°C for 3 months under sterile conditions after reconstitution.
 

电泳(SDS-PAGE)

Biotinylated Human EpCAM, His Tag (Cat. No. EPM-H8223) SDS-PAGE gel

Biotinylated Human EpCAM, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.

背景(Background)

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.
