Extended validation for CD326 (EpCAM) Antibody, anti-human, REAfinity™

Specificity

Epitope competition
In order to compare the epitope specificity of an antibody, the clone being used is compared with other known clones recognizing the same antigen in a competition assay.

Cells were incubated with an excess of purified unconjugated CD326 (EpCAM) (REA764) antibody followed by staining with fluorochrome-conjugated antibodies of other known clones against the same marker. Based on the fluorescence signal obtained, the clones were identified as recognizing completely overlapping (++), partially overlapping (+), or completely different epitopes (-) of the marker.

Sensitivity

Performance comparison
Selected fluorochrome conjugated antibodies from Miltenyi Biotec were compared to commercially available hybridoma clones in flow cytometry analysis.

Flow cytometric comparison of different clones for CD326 (EpCAM). SK-BR-3 cells were stained with CD326 (EpCAM) antibodies and plotted against the side scatter. As a control, CD326 (EpCAM) antibody staining was omitted and cells were measured in the same channels. Flow cytometry was performed with the MACSQuant® Analyzer. Cell debris, dead cells, and cell doublets were excluded from the analysis based on scatter signals and 4',6-diamidino-2-phenylindole (DAPI) fluorescence. The recommended titers of respective antibodies from different suppliers were used.

Fixation data
To provide an indication on how an antibody performs after fixation of cells, in-house data on staining results before and after fixation with 3.7% formaldehyde using Miltenyi Biotec antibodies are provided. Different experimental settings may lead to different results.

Specifications for CD326 (EpCAM) Antibody, anti-human, REAfinity™

Overview

Clone REA764 recognizes CD326, also known as human epithelial antigen (HEA), epithelial cell adhesion molecule (EpCAM), or epithelial-specific antigen (ESA), and is involved in cell adhesion. The CD326 antigen is broadly expressed on the basolateral surface of carcinoma and epithelial cells in tissues or on circulating tumor cells and cancer stem cells, but is not found on melanoma, neuroblastoma, sarcoma, lymphoma, leukemia cells, or normal fibroblasts. Furthermore, it is suggested, that CD326 could be used as a surface marker for human ESCs.
Additional information: Clone REA764 displays negligible binding to Fc receptors.
