by staining the cells simultaneously with two different fluorescent markers : the cell surface hme antigens with fluorescein-tagged antibodies ( green fluorescence ) and the cell dna with propidium iodide ( red fluorescence ) , it was possible to determine the expression of hme antigens per unit dna , analyze their expression on breast cells in mixed populations , and analyze their expression in different phases of the cell cycle .
