Product Overview
This rabbit polyclonal antibody detects protein jagged-1 (gene JAG1) in human samples and is validated for Western blot, flow cytometry and ELISA. The predicted molecular weight is 133.8 kDa, and the supplier reports an observed band at about 180 kDa.
Jagged-1 (JAG1) is a cell surface ligand for Notch receptors. By contacting Notch on neighboring cells, it drives cell fate decisions in the heart, blood vessels, liver bile ducts, inner ear and hematopoietic system. Mutations in JAG1 cause Alagille syndrome, and it is a standard target in Notch signaling research.

Samples with a confirmed band (WB): human HepG2 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 a confirmed signal (flow cytometry): HepG2 cells.
Immunogen
Recombinant human Jagged1/JAG1 fragment (Ala994–Val1218), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human. UniProt places protein jagged-1 in the membrane and cell membrane. Tissue expression noted by UniProt (human): Widely expressed in adult and fetal tissues. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
