Product Overview
Clone GBG-5 is a rabbit monoclonal antibody that recognizes epithelial cell adhesion molecule (gene EPCAM) in human samples and is validated for Western blot and IHC. The predicted molecular weight is 34.9 kDa, and the supplier reports an observed band at about 35 kDa.
EpCAM (CD326) is a transmembrane glycoprotein on most epithelial cells that mediates homophilic cell-cell adhesion. It also influences proliferation and stem cell maintenance, and it is highly expressed in many carcinomas. EpCAM is widely used to identify and isolate epithelial and circulating tumor cells, and EPCAM mutations cause congenital tufting enteropathy.

Validated Applications
| Western blot | 1:1000–1:2000 |
|---|---|
| Immunohistochemistry | 1:50–1:200 |
Samples with confirmed staining (IHC): human stomach carcinoma tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Immunogen
Synthetic peptide based on the sequence of human epCAM.
Reactivity Notes
The supplier lists reactivity with human. UniProt places epithelial cell adhesion molecule in the lateral cell membrane and cell junction. Tissue expression noted by UniProt (human): Highly and selectively expressed by undifferentiated rather than differentiated embryonic stem cells (ESC). The samples tested by the supplier (listed above) are a practical starting point for positive controls.

Customization & Add-ons: Can’t find the antibody you need—or require a custom format for your assay? We can help you source the best match or support custom antibody solutions for diverse research needs, including species and isotype selection, conjugations and labeling (e.g., HRP/AP, biotin, fluorophores), purification grade options (Protein A/G, affinity purified), formulation preferences (buffer selection, carrier-free, glycerol-free), custom concentrations and aliquoting, low-endotoxin options for cell-based work, and application-focused QC/validation support (project dependent).
