General Description
FITC (fluorescein isothiocyanate) is a fluorophore that absorbs ultraviolet or blue light and emits visible yellow-green light. Fluorescent labeling allows quick and precise localization of antigen-antibody associations in tissues and cells. FITC is a widely used antibody marker in immunofluorescence assays, as protein-FITC conjugation is comparatively a simple task and usually does not interfere with protein function. FITC is also utilized as a hapten to label proteins. Thus, anti-FITC antibodies can facilitate the analyses of FITC labeled proteins and antibody responses to haptens.
