Energy transfer between fluorescein isothiocyanate and propidium iodide--a problem in the estimation of Tpot with the bromodeoxyuridine-DNA flow cytometry technique?
Energy transfer in flow cytometry can occur when two fluorochromes are bound in close proximity (generally within 100 A) and the emission spectrum of one fluorochrome overlaps significantly with the excitation spectrum of the other. The latter criterium is fulfilled for the fluorochromes fluorescein isothiocyanate and propidium iodide and also the former when they, e.g., are used in bromodeoxyurid
