Fluorescein has an absorption maximum at 494 nm and emission maximum of 512 nm (in water). The major derivatives are fluorescein isothiocyanate (FITC) and, in oligonucleotide synthesis, 6-FAM phosphoramidite. In cellular biology, the isothiocyanate derivative of fluorescein is often used to label and track cells in fluorescence …
