Dendrotoxin-I

Catalog No.: A13926
K+ Channel Blocker
Dendrotoxin-I (DTX-I) is a potent inhibitor of voltage-gated potassium channels, specifically targeting the KV1.1, KV1.2, and KV1.6 subunits with IC50 values ranging from 0.13 to 50 nM. This neurotoxin exhibits significant biological activity that can influence neuronal excitability and synaptic transmission. Dendrotoxin-I is primarily utilized in research applications related to cancer and neurobiology, providing insights into ion channel function and their roles in disease mechanisms.
