Product Overview
This rabbit polyclonal antibody targets sodium/hydrogen exchanger 2 (gene SLC9A2) in human, mouse and rat samples and is validated for Western blot and IHC. The predicted molecular weight is 91.5 kDa, and the supplier reports an observed band at about 91 kDa.
NHE2 (SLC9A2) is a plasma membrane Na+/H+ exchanger found at the apical surface of epithelial cells. In the colonic crypt it controls intracellular pH and has been linked to the choice between absorptive and secretory cell fates.

Validated Applications
| Western blot | 0.1–0.5 µg/mL (Mouse, Rat) |
|---|---|
| IHC (paraffin sections) | 0.5–1 µg/mL (Human, Rat) |
Samples with a confirmed band (WB): rat kidney tissue, mouse kidney 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 lung cancer tissue, rat kidney 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 citrate buffer (pH 6).
Immunogen
Synthetic peptide from the C-terminal region of human SLC9A2. It differs from the rat and mouse sequences at two residues.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places sodium/hydrogen exchanger 2 in the apical cell membrane. Tissue expression noted by UniProt (human): Expressed in skeletal muscle, colon and kidney. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
