Product Overview
This rabbit polyclonal antibody detects bone morphogenetic protein 4 (gene BMP4) in human, mouse and rat samples and is validated for Western blot. The predicted molecular weight is 46.6 kDa, and the supplier reports an observed band at about 47 kDa.
Bone morphogenetic protein 4 (BMP4) is a TGF-β superfamily growth factor that activates SMAD1/5/8 through BMP receptors. It patterns the early embryo, including ventral mesoderm and epidermal fates, and regulates bone, kidney, lung and tooth development, and it is widely used to direct stem cell differentiation in culture.

Validated Applications
| Western blot | 0.1–0.5 µg/mL |
|---|
Samples with a confirmed band (WB): human HepG2 cells, human U2OS cells, human Caco-2 cells, rat lung tissue, mouse lung tissue.
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.
Immunogen
Recombinant human BMP4 fragment (Ser293–Arg408), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. Tissue expression noted by UniProt (human): Expressed in the lung and lower levels seen in the kidney. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
