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. Alpha-bungarotoxin may also be used for detection of GABA A receptor subsets in cells (1), or for labeling recombinant proteins that express the alpha-bungarotoxin binding site (BBS) epitope tag (2).

  • 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.
