Stromatoxin 1

Catalog No.: A68268
Potassium Channel Inhibitor
Stromatoxin 1 is a selective inhibitor of potassium channels, specifically targeting K(V)2.1, K(V)2.2, and K(V)4.2 subunits. This peptide, derived from tarantulas, has been shown to effectively modulate smooth muscle contractions in the urinary bladder by inhibiting the activity of K(V)2.1 and K(V)2.2 channels, while having no effect on K(V)4.2. It serves as a valuable tool for research into bladder physiology and the electrophysiological properties of potassium channels.
