Detection of Human Integrin alpha 1/CD49a by Western Blot. Western blot shows lysates of SH‑SY5Y human neuroblastoma cell line. PVDF membrane was probed with 1 µg/mL of Sheep Anti- Human Integrin alpha 1/CD49a Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5676) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for Integrin alpha 1/CD49a at approximately 200 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.
Detection of Integrin alpha 1/CD49a in HeLa Human Cell Line by Flow Cytometry. HeLa human cervical epithelial carcinoma cell line was stained with Sheep Anti-Human Integrin alpha 1/CD49a Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5676, filled histogram) or isotype control antibody (Catalog # 5-001-A, open histogram), followed by Phycoerythrin-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # F0126).
Integrin alpha 1/CD49a in Human Stomach Cancer Tissue. Integrin alpha 1/CD49a was detected in immersion fixed paraffin-embedded sections of human stomach cancer tissue using Sheep Anti-Human Integrin alpha 1/CD49a Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5676) at 10 µg/mL overnight at 4 °C. Before incubation with the primary antibody tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained using the Anti-Sheep HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS019) and counterstained with hematoxylin (blue).

Background: Integrin alpha 1/CD49a
Integrin alpha 1 (also VLA-1, CD49a and Laminin and Collagen Receptor) is a 190‑210 kDa member of the integrin alpha chain family of molecules. It is found on smooth muscle cells, osteoblasts, adipocytes and intestinal epithelium. Integrin alpha 1 forms a noncovalent heterodimer with Integrin beta 1, and serves as a divalent-cation dependent receptor for collagen types I, IV, VI, XIII and XVI. It also binds the diarrhea-associated NSP4 enterotoxin of rotavirus. Mature human Integrin alpha 1 is a 1151 amino acid (aa) type I transmembrane glycoprotein that contains a 1113 aa extracellular domain (ECD) and a 15 aa cytoplasmic tail. The ECD contains one vWFA/I‑domain (aa 147‑360) that binds collagen, plus multiple divalent cation binding sites. Potential splice variants exist that show a two and four aa substitution for aa 765‑1179. Over aa 29‑1141 (the ECD), human Integrin alpha 1 shares 88% aa identity with mouse Integrin alpha 1.
