General description
La toxina del cólera y su subunidad A suelen utilizarse para estudiar los mecanismos de transducción de la señal debido a su impacto en la adenilato ciclasa. Además, la toxina del cólera actúa como un adyuvante estimulando las respuestas de los linfocitos B y los linfocitos T auxiliares tipo 2 al inhibir la producción de interleucina-12. La subunidad B no tóxica (CTB) se fija a las células uniéndose al gangliósido GM1, lo que la convierte en una etiqueta útil para las células microgliales en la investigación neurológica. También se ha demostrado que es un excelente marcador para estudios de transporte axónico utilizando métodos inmunohistoquímicos.

Hey, Can this product be reconstituted to a solution and administered to mice for systemic upregulation of immune cells?
1 respuesta-
This product has not been tested for use in animal models, however, the preparation does contain sodium azide as a preservative. Azide is reported to have an LD50 of 19 mg/kg in mouse by I.V. route. This is not a sterile preparation, solutions would require filter sterilization prior to in vitro or in vivo use. Please see the link below to review the product datasheet:
