Product Overview
This rabbit polyclonal antibody recognizes integrin alpha-1 (gene ITGA1) in human, mouse and rat samples and is validated for Western blot and IHC. The predicted molecular weight is 130.8 kDa, and the supplier reports an observed band at about 190–200 kDa.
Integrin alpha-1 (ITGA1, CD49a) pairs with integrin beta-1 to form VLA-1, a receptor for collagens, especially type IV collagen, and laminin. It is expressed on mesenchymal cells and activated or tissue-resident T cells, and it mediates cell adhesion and signaling that can restrain growth factor–driven proliferation.

Validated Applications
| IHC (paraffin sections) | 0.5–1 µg/mL (Human, Rat, Mouse) |
|---|---|
| Western blot | 0.1–0.5 µg/mL (Human, Rat, Mouse) |
Samples with a confirmed band (WB): human HeLa cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with confirmed staining (IHC): human esophageal squamous carcinoma tissue, human lung adenocarcinoma tissue, human placenta tissue, human liver cancer tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Conditions in the example images (IHC): heat-mediated antigen retrieval in EDTA buffer (pH 8.0).
Immunogen
Synthetic peptide from the C-terminal region of human integrin alpha 1. It differs from the mouse and rat sequences at one residue.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places integrin alpha-1 in the membrane. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
