Product Overview
This rabbit polyclonal antibody detects exportin-5 (gene XPO5) in human, mouse and rat samples and is validated for Western blot. The predicted molecular weight is 136.3 kDa, and the supplier reports an observed band at about 136 kDa.
Exportin-5 (XPO5) is a Ran-GTP-dependent nuclear export receptor that recognizes double-stranded RNA structures. Its best-known cargo is pre-microRNA hairpins produced by Drosha, which it carries to the cytoplasm for Dicer processing, and it also exports certain tRNAs and dsRNA-binding proteins, so it is central to studies of microRNA biogenesis.

Validated Applications
| Western blot | 0.1–0.5 µg/mL (Human, Mouse, Rat) |
|---|
Samples with a confirmed band (WB): human HeLa cells, human K562 cells, human HEL 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.
Immunogen
Synthetic peptide from the N-terminal region of human exportin-5. It differs from the mouse sequence at four residues.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places exportin-5 in the nucleus and cytoplasm. Tissue expression noted by UniProt (human): Expressed in heart, brain, placenta, lung, skeletal muscle, kidney and pancreas. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
