Cholera toxin


List Labs’ products in the Cholera toxin group

  • 100 Cholera toxin
  • 104 Cholera toxin B subunit (CTB)
  • 106 Cholera toxin B subunit attached to FITC
  • 112 Cholera toxin B subunit attached to Biotin
  • Export license is required for international customers. £50.00 fee will be added to each shipment.

Key attributes

Toxins are produced in native organisms and provided at >95% purity. Cholera toxin B subunit is derived from the native whole toxin and purified.  Endotoxin within the preparations is low, and the measurement value is provided. Activity of both the toxin and the B subunit is assessed by binding to the natural target, GM1 gangliosides.

Additional products supporting research using Cholera toxin

  • 703 Anti-CTB antibody raised in goat

Potential customers:

Scientists, associated with universities and small businesses, use Cholera toxin as a tool to stimulate the growth of cells in culture and to induce an immune response. Cell biologists are interested in investigating the pathways disturbed by Cholera toxin.

They also use Cholera B subunit and the companion antibody (product # 703) to label and identify neuronal paths. These products may be used for research purposes in hospital laboratories, universities and companies. They are not for use in humans and are not approved for diagnostic purposes.

Specific requirements

Cholera toxin and the B subunit can both be handled in a laboratory setting using good laboratory techniques. They are not for use in humans and are not approved for diagnostic purposes.

Technical information

Briefly, Cholera toxin is an interesting research tool because, it is playing a part in stem cell research; cholera toxin can promote the growth of stem cells. It may be used to stimulate the growth of cells in culture, potentially creating material to be transplanted first in animals and eventually in humans.

There are reports in the literature of cholera toxin used to produce corneal transplants and nerve tissue. In a similar application, Cholera toxin is used to stimulate cells which produce blood, and when transferred in vivo, move and settle into bone marrow.

Cholera toxin B subunit is a tool in research focused on regenerating damaged nerves. Labeling of neurons with cholera toxin B subunit has been used to demonstrate the generation and repair of peripheral nerves by a transcription factor KLF7.

Cholera toxin, a tool for cell biology, has been used to understand the role of the endoplasmic-reticulum-associated protein degradation (ERAD) pathway. Cholera toxin hijacks this basic cellular path, using ERAD chaperone proteins to retro-translocate from the ER to the cytosol.
