Product Overview
This rabbit polyclonal antibody targets caveolin-3 (gene CAV3) in human, mouse and rat samples and is validated for ELISA, ICC/IF, IHC and Western blot. The predicted molecular weight is 17.3 kDa, and the supplier reports an observed band at about 22 kDa.
Caveolin-3 (CAV3) is the muscle-specific caveolin that forms caveolae in skeletal and cardiac muscle cells. It organizes signaling molecules and ion channels at the sarcolemma and supports membrane repair together with dysferlin. Mutations in CAV3 cause caveolinopathies, including a form of limb-girdle muscular dystrophy and rippling muscle disease.

Samples with a confirmed band (WB): human placenta tissue, human U-87MG cells, human HeLa cells, rat stomach tissue, rat testis tissue, mouse stomach tissue, mouse testis tissue.
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, 50 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 1:10000, ECL detection.
Samples with confirmed staining (IHC): human skeletal muscle 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).
Samples with confirmed staining (ICC/IF): human cardiac muscle tissue, mouse cardiac muscle tissue, rat cardiac muscle tissue.
Immunogen
Recombinant human Caveolin-3/CAV3 fragment (Met1–Asp55), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places caveolin-3 in the Golgi apparatus membrane, cell membrane and membrane. Tissue expression noted by UniProt (human): Expressed predominantly in muscle. 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).
