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

Biochem/physiol Actions

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.

Physical form

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

Analysis Note

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.

고리형 뉴클레오타이드를 위한 생체 활성 저분자

고리형 AMP(cAMP), 고리형 GMP(cGMP), 고리형 ADP-리보스를 포함하여 고리형 뉴클레오타이드는 GPCR 활성화에 의해 개시된 세포내 이벤트의 2차 전달자로서 광범위하게 연구되었습니다. cAMP는 주로 cAMP 의존성 단백질 인산화효소(PKA)의 활성화를 통해 모든 진핵생물 세포에서 세포 기능을 변형시키지만 cAMP 개폐 이온 채널 및 cAMP에 의해 직접 활성화되는 구아닌 뉴클레오타이드 교환 인자를 통해서도 변형시킵니다.
