BeKm-1（Cat No.:P000320）is a peptide toxin derived from the venom of the Central Asian scorpion Buthus eupeus. This peptide is known for its ability to block potassium channels, specifically the Kv1.1 and Kv1.3 subtypes, which play crucial roles in various physiological processes, including the regulation of immune responses and neuronal excitability. Due to its selective binding to these channels, BeKm-1 is used in neurophysiological studies to explore potassium channel function and has potential therapeutic applications in treating autoimmune diseases and neurological disorders by modulating immune cell activity.
