Application

Cholera Toxin B subunit-fluorescein isothiocyanate (FITC) conjugate has been used as a fluorescent tracer:
  • to label distal cerebrospinal fluid-contacting neurons (dCSF-CNs) in lateral ventricles of rat
  • to stain epididymal sperms of mice
  • to stain peritoneal macrophages of mice

Actions biochimiques/physiologiques

La sous-unité B de la toxine cholérique est utilisée pour le traçage de voies en recherche neurologique, tirant profit de la liaison au ganglioside GM1 et du transport rétrograde. Les cellules issues de cultures cellulaires traitées avec de la toxine cholérique ne sont pas tuées, et les tissus animaux ne deviennent pas nécrotiques.

Forme physique

Lyophilized powder containing Tris buffer salts, sodium chloride, sodium EDTA and sodium azide

Remarque sur l'analyse

Activity measured by ELISA using ganglioside GM1 coated multiwell plates, rabbit anti-cholera toxin B subunit antibodies, and peroxidase-labeled goat anti-rabbit IgG as the second antibody. 50% saturation of binding was achieved with 0.01-1 μg of the cholera toxin B subunit-FITC conjugate per mL.
