What are Some Common Fluorescent Molecules?

Several well-known fluorescent molecules are frequently used in histology:

FITC (Fluorescein isothiocyanate): Emits green fluorescence and is commonly used for labeling antibodies.
TRITC (Tetramethylrhodamine isothiocyanate): Emits red fluorescence and is another popular choice for antibody labeling.
DAPI (4',6-diamidino-2-phenylindole): Binds strongly to DNA and emits blue fluorescence, making it ideal for nuclear staining.
Alexa Fluor dyes: A series of dyes with different emission spectra, offering a broad range of colors for multiplexing.
