when cells are exposed first to opsonized zymosan particles , which they can phagocytize , then to a combination of these fluorescent dyes , one can distinguish microscopically between dead cells with fluorescent red nuclei , live cells which fluoresce green , and live cells with phagocytic function which are swollen with the pink zymosan particles in a green fluorescing cytoplasm .
