Product Description

A potent neurotoxin that is an inhibitor for the motor endplate acetylcholine receptor (Kd = 1 nM to 1 pM). It binds at the neuromuscular junction with high affinity and is often used to study neuromuscular junctions by blocking cholinergic receptors. The toxin also blocks α7 receptors, located in the central and peripheral nervous systems.

  • A polypeptide snake toxin
  • Blocks and inhibits cholinergic receptors
  • White solid soluble in water

Also see our Fluorescent α-Bungarotoxins and Biotin α-Bungarotoxin which can can be used for labeling of nicotinic acetylcholine receptors at neuromuscular junctions in tissue sections. See our complete selection of α-Bungarotoxins below.
