| Background | Epithelial Cell Adhesion Molecule (EpCAM), also known as GA733-2 antigen, is a type â-€¦transmembrane glycoprotein composed of an extracellular domain with two EGF-Like repeats and a cystenin-rich region, a transmembrane domain and a cytoplasmic domain. It modulates cell adhesion and proliferation. Its overexpression has been detected in many epithelial tumours and has been associated with high stage, high grade and a worse survival in some tumour types. EpCAM has been shown to function as a calcium-independent homophilic cell adhesion molecule that does not exhibit any obvious relationship to the four known cell adhesion molecule superfamilies. However, recent insights have revealed that EpCAM participates in not only cell adhesion, but also in proliferation, migration and differentiation of cells. In addition, recent study revealed that EpCAM is the Wnt-beta-catenin signaling target gene and may be used to facilitate prognosis. It has oncogenic potential and is activated by release of its intracellular domain, which can signal into the cell nucleus by engagement of elements of the wnt pathway.Immune CheckpointImmunotherapyCancer ImmunotherapyTargeted Therapy |
| Description | A DNA sequence encoding the extracellular domain (Met 1-Lys265) of human EpCAM (NP_002345.1) was fused with a His tag at the C-terminus. |
| Source | HEK293 |
| Predicted N Terminal | Gln 24 |
| AA Sequence | Met 1-Lys265 |
| Molecular Weight | The recombinant human EpCAM consists of 253 a.a. after removal of the signal peptide and has a calculated molecular mass of 29 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rh EpCAM is approximately 36 kDa due to glycosylation. |
| Purity | >96% as determined by SDS-PAGE |
| Endotoxin | < 1.0 EU per μg of the protein as determined by the LAL method |
| Bioactivity | Measured- by- the- ability- of- the- immobilized- protein- to- support- the- adhesion- of- NIH-3T3 mouse embryonic fibroblast cells. When cells are added to EpCAM-His coated plates (1.25ug/mL,- 100uL/well), approximately >40% will adhere specifically after 30 minutes at 37°C. |
| Formulation | Lyophilized from sterile PBS, pH 7.4. |
| Stability | The recombinant proteins are stable for up to 1 year from date of receipt at -70°C. |
| Usage | For Research Use Only |
| Storage | Store the protein under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles. |
