Product Description

Alpha-bungarotoxin is a polypeptide snake toxin that binds to the nicotinic acetylcholine receptor found at the neuromuscular junction with high affinity. Fluorescent alpha-bungarotoxin can be used for labeling of nicotinic acetylcholine receptors at neuromuscular junctions in tissue sections.

  • Choose from 9 bright and stable CF® Dye colors or other labels
  • Dye options for super-resolution and 2-photon imaging

We also offer Biotin-XX-alpha-bungarotoxin (catalog. no. 00017), and unconjugated alpha-bungarotoxin.(catalog no. 00010-1). See our complete selection of alpha-Bungarotoxins below.

Superior CF® Dyes

Biotium’s next-generation CF® dyes were designed to be highly water-soluble with advantages in brightness and photostability compared to Alexa Fluor®, DyLight®, and other fluorescent dyes. Learn more about CF® Dyes.

Super-Resolution Microscopy

Many CF® dyes are compatible with super resolution imaging, CF® dyes give the best performance for multiple methods. The superior brightness, photostability, and photochemical switching properties of certain CF® dyes are ideal for 3-D SIM, 3-D STORM, and other super-resolution and single-molecule imaging approaches. Learn more about CF® dyes for super-resolution microscopy.
