What is CHOLERA TOXIN B SUBUNIT?

The Uses of CHOLERA TOXIN B SUBUNIT

Cholera Toxin B subunit has been used:

for macrophage stimulation and i.p. injection in a study to determine the endotoxin sensitivity of Caspase-4.
in transganglionic and retrograde tract-tracing method combined with dual-immunofluorescence histochemistry of adult rat Vmes neuron cells.

The Uses of CHOLERA TOXIN B SUBUNIT

Cholera Toxin B subunit has been used as a tracer to study the ascending projections of the nuclei of the descending trigeminal tract (nTTD) in the zebra finch.

General Description

The advantage of this product over the native CTXB is that it has no traces of Vibrio cholera, and no contamination of the highly toxic Cholera toxin A subunit. This product is expressed in human HEK 293 cells as a C-terminally his-tagged protein with a calculated molecular mass of 13 kDa (amino acids Thr22-Asn124).

Biochem/physiol Actions

Cholera Toxin B subunit stimulates both systemic and mucosal antibody production in animals and humans. CTB functions as an oral subunit vaccine for cholera, which is associated with acute watery diarrhoea.
