Fluoresceína 5-isotiocianato

Descripción:

Fluoresceína 5-isotiocianato (FITC) es un colorante fluorescente comúnmente utilizado en investigación biológica e inmunología para etiquetar proteínas, anticuerpos y ácidos nucleicos. Se caracteriza por su brillante fluorescencia verde cuando es excitado por luz ultravioleta o azul, lo que lo convierte en un excelente marcador para microscopía de fluorescencia y citometría de flujo. El compuesto presenta una estructura de fluoresceína, que contribuye a sus fuertes propiedades de fluorescencia, y un grupo funcional isotiocianato que facilita el enlace covalente a grupos amino en proteínas. FITC es soluble en disolventes orgánicos y agua, lo que permite aplicaciones versátiles en diversas condiciones experimentales. Su reactividad con aminas primarias permite la formación de conjugados estables, que son cruciales para rastrear biomoléculas en células o tejidos vivos. Sin embargo, es importante manejar FITC con cuidado, ya que puede ser sensible a cambios de pH y exposición a la luz, lo que puede afectar su intensidad de fluorescencia. En general, FITC es una herramienta valiosa en el campo de la bioquímica y la biología molecular para visualizar y estudiar procesos celulares.

Fluorescein isothiocyanate Isomer I

CAS: 3326-32-7

Fluorescent labeling reagent for proteins. FITC-conjugated antibodies are commonly used in immunohistochemistry for immunofluorescent staining. Fluorescein isothiocyanate (FITC) is a yellow-green colored low molecular weight dye which couples to proteins via reaction with primary amine groups at high pH. FITC is excitable at 488nm, close to its absorption maximum at 494nm, and produces maximum fluorescence emission around 520nm. It is commonly conjugated with antibodies for use in indirect immunofluorescence.
