Cholera Toxin (AZIDE-FREE) from Vibrio cholerae
Cholera toxin is an oligomeric protein of
MW 84,000 daltons
which consists of a single A subunit surrounded by five B subunits. It is
a potent activator of adenylate cyclase and is the pathogenic agent responsible
for the symptoms of cholera.
Cholera toxin has become a powerful
research tool not only in microbiology, but in the fields of physiology, cell
biology and biochemistry, as well. Because of the effect on adenylate cyclase,
cholera toxin is frequently used for the study of signal transduction
mechanisms. In addition, cholera toxin acts as an adjuvant through the
stimulation of B-lymphocytes. The cholera toxin B subunit alone is used for
track tracing in neurological research, taking advantage of GM1 ganglioside
binding and retrograde transport.
