Human AG-3 Antibody Summary

Species Reactivity

Human

Specificity

Detects human AG-3 in direct ELISAs and Western blots. In direct ELISAs, less than 1% cross-reactivity with recombinant human AG‑2 is observed.

Source

Detection of Human AG‑3 by Western Blot. Western blot shows lysates of human small intestine tissue. PVDF Membrane was probed with 0.5 µg/mL of Human AG-3 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6307) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for AG-3 at approximately 19kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Immunohistochemistry

AG‑3 in Human Breast. AG-3 was detected in immersion fixed paraffin-embedded sections of human breast using Sheep Anti-Human AG-3 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6307) at 3 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Sheep HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS019) and counterstained with hematoxylin (blue). Specific staining was localized to epithelial cells.

Background: AG-3

AG3 (Anterior gradient protein 3; also known as AGR3 and BCMP11) is a 17 kDa (predicted) member of the AGR family of proteins. It is expressed by intestinal epithelial and breast cancer cells. AG3 is presumably secreted and binds to both a-dystroglycan and C4.4a/LYPD3. Mature human AG3 is 145 amino acids (aa) in length (aa 22‑166) (SwissProt #:Q8TD06). Over aa 22-166, human AG3 shares 92% amino acid sequence identity with mouse AG3.
