lamb kidney β subunit of Na+/K+ ATPase.

General description

Epitope mapping studies indicate that this clone recognizes the epitope between amino acids 195 and 199 of the sheep β1 subunit of Na+/K+ ATPase. Staining is consistent with the plasma membrane localization of Na+/K+ ATPase.

Mouse monoclonal anti-Na+/K+ ATPase (β1 subunit) reacts with the β1 subunit of Na+/K+ ATPase in humans, sheep, canines and pigs, but not in rats. The product shows no reactivity with rat β2 subunit. In immunoblotting, the antibody detects the β1 subunit of Na+/K+ ATPase as a 42kDa band in liver samples, and as a 52kDa band in kidney samples.

Na+/K+ transporting ATPase subunit α1 is an ion transport pump critical for maintaining the gradient of Na and K ions across the plasma membrane.
