Product Overview
This rabbit polyclonal antibody detects BPI fold-containing family A member 1 (gene BPIFA1) in human and mouse samples and is validated for Western blot and ELISA. The predicted molecular weight is 26.7 kDa, and the supplier reports an observed band at about 27 kDa.
BPIFA1 (also called SPLUNC1) is a secreted protein of the BPI fold family made by airway epithelium, especially in the nose and upper airways. It binds surfactant lipids and has surfactant-like and antimicrobial activities, and it helps regulate airway surface liquid volume by inhibiting the epithelial sodium channel ENaC.

Validated Applications
| Western blot | 0.25–0.5 µg/mL (Mouse) |
|---|---|
| ELISA | 0.1–0.5 µg/mL |
Samples with a confirmed band (WB): mouse NIH/3T3 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
Recombinant human Plunc/BPIFA1 fragment (Leu64–Val256), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human and mouse. UniProt describes BPI fold-containing family A member 1 as a secreted protein. Tissue expression noted by UniProt (human): Highly expressed in lung, upper airways and nasopharyngeal regions, including trachea and nasal epithelium (at protein level). The samples tested by the supplier (listed above) are a practical starting point for positive controls.
