Scientific Data Images for Human Claudin‑3 Antibody

Detection of Claudin‑3 in PC‑3 Human Cell Line by Flow Cytometry.

PC-3 human prostate cancer cell line was stained with Mouse Anti-Human Claudin-3 Monoclonal Antibody (Catalog # MAB4620, filled histogram) or isotype control antibody (Catalog # MAB003, open histogram), followed by Phycoerythrin-conjugated Anti-Mouse IgG F(ab')₂Secondary Antibody (Catalog # F0102B).

Claudin‑3 in Human Colon.

Claudin-3 was detected in immersion fixed paraffin-embedded sections of human colon array using Mouse Anti-Human Claudin-3 Monoclonal Antibody (Catalog # MAB4620) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue). Lower panel shows a lack of labeling if primary antibodies are omitted and tissue is stained only with secondary antibody followed by incubation with detection reagents.

Claudin‑3 in PC‑3 Human Cell Line.

Claudin-3 was detected in immersion fixed PC-3 human prostate cancer cell line using Mouse Anti-Human Claudin-3 Monoclonal Antibody (Catalog # MAB4620) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

Background: Claudin-3

Claudin-3 is a 23 kDa multipass membrane protein in the claudin family of epithelial tight junction proteins. Claudin-3 is upregulated by EGF and in inflammation and a variety of epithelial cancers. Its expression is lost in the blood brain barrier during pathological disruptions of that structure. Claudin-3 binding to the Clostridium perfringes exotoxin induces epithelial cell lysis. Human Claudin-3 shares 91% amino acid sequence identity with mouse and rat Claudin-3.
