Product Overview
This rabbit polyclonal antibody targets inactive rhomboid protein 2 (gene RHBDF2) in human samples and is validated for Western blot, flow cytometry and ELISA. The predicted molecular weight is 96.7 kDa, and the supplier reports an observed band at about 97 kDa.
RHBDF2 (iRhom2) is a catalytically inactive member of the rhomboid family that lives in the endoplasmic reticulum. It escorts the sheddase ADAM17 to the cell surface and controls its activity, which is needed for release of TNF and EGF receptor ligands. iRhom2 is studied in inflammation, especially in macrophages, and RHBDF2 mutations cause tylosis with esophageal cancer.

Samples with a confirmed band (WB): human MCF-7 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 RHBDF2 fragment (His145–Asp529), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human. UniProt places inactive rhomboid protein 2 in the endoplasmic reticulum membrane and cell membrane. Tissue expression noted by UniProt (human): Found in the epidermis and esophageal epithelium. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
