일반 설명

Cholera Toxin is a heterohexameric AB5 enterotoxin. Cholera Toxin B subunit is the the B subunit pentamer of cholera toxin produced by Vibrio cholera. It is generally involved in the cell trafficking and signalling machineries.

애플리케이션

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.

생화학적/생리학적 작용

The cholera toxin B subunit is used for track tracing in neurological research, taking advantage of GM1 ganglioside binding and retrograde transport.
The cholera toxin B subunit is used for track tracing in neurological research, taking advantage of GM1 ganglioside binding and retrograde transport. Tissue culture cells treated with cholera toxin are not killed and tissues of animals do not become necrotic.

물리적 형태

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

재구성

When reconstituted with water to a final concentration of 1 mg of CTB per ml, the solution will contain 0.05 M Tris buffer, pH 7.5, 0.2 M NaCl, 3 mM NaN3 and 1 mM sodium EDTA.

분석 메모

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 secondary antibody. 50% saturation of binding was achieved with 0.05-1 μg of Cholera toxin B subunit per mL.

Cyclic nucleotides, including cyclic AMP (cAMP), cyclic GMP (cGMP) and cyclic ADP-ribose, have been extensively studied as second messengers of intracellular events initiated by activation of GPCRs. cAMP modifies cell function in all eukaryotic cells, principally through the activation of cAMP-dependent protein kinase (PKA), but also through cAMP-gated ion channels and guanine nucleotide exchange factors directly activated by cAMP.
