Product Overview
This rabbit polyclonal antibody targets vitronectin (gene VTN) in human, mouse and rat samples and is validated for IHC and Western blot. The predicted molecular weight is 54.3 kDa, and the supplier reports an observed band at about 65–70 kDa.
Vitronectin is a glycoprotein abundant in plasma and the extracellular matrix. It binds integrins such as αvβ3 to support cell adhesion and spreading, stabilizes the protease inhibitor PAI-1, and limits formation of the membrane attack complex of complement. Vitronectin is studied in cell adhesion, fibrinolysis and tissue repair.

Validated Applications
| IHC (paraffin sections) | 0.5–1 µg/mL (Human) |
|---|---|
| Western blot | 0.1–0.5 µg/mL (Human, Mouse, Rat) |
Samples with a confirmed band (WB): human hepatocellular carcinoma tumor tissue, human hepatocellular carcinoma paracancerous tissue, mouse plamsa lysates.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 10% 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 lung cancer tissue, human breast 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 vitronectin. It differs from the mouse sequence at two residues.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt describes vitronectin as a secreted protein. Tissue expression noted by UniProt (human): Expressed in the retina pigment epithelium (at protein level). The samples tested by the supplier (listed above) are a practical starting point for positive controls.

Customization & Add-ons: Can’t find the antibody you need—or require a custom format for your assay? We can help you source the best match or support custom antibody solutions for diverse research needs, including species and isotype selection, conjugations and labeling (e.g., HRP/AP, biotin, fluorophores), purification grade options (Protein A/G, affinity purified), formulation preferences (buffer selection, carrier-free, glycerol-free), custom concentrations and aliquoting, low-endotoxin options for cell-based work, and application-focused QC/validation support (project dependent).
