Product Overview
This rabbit polyclonal antibody targets epithelial sodium channel subunit alpha (gene SCNN1A) in human samples and is validated for ICC/IF and Western blot. The predicted molecular weight is 75.7 kDa, and the supplier reports an observed band at about 76 kDa.
SCNN1A encodes the α subunit of the epithelial sodium channel (ENaC), which forms the channel together with β and γ subunits. ENaC lets sodium enter across the apical membrane of kidney, lung and colon epithelia, controlling sodium balance, blood pressure and airway surface liquid volume.

Immunogen
Synthetic peptide from the C-terminal region of human SCNN1A. Sequence identity with the mouse and rat orthologs: 83.3%.
Reactivity Notes
The supplier lists reactivity with human. UniProt places epithelial sodium channel subunit alpha in the apical cell membrane, cell projection, cytoplasmic granule and cytoplasm. Tissue expression noted by UniProt (human): Expressed in the female reproductive tract, from the fimbrial end of the fallopian tube to the endometrium (at protein level). The samples tested by the supplier (listed above) are a practical starting point for positive controls.
