using different specimens of the stain the accuracy and sensitivity of the cytofluorometric method were estimated by the next parameters : the value of the useful signal from the nucleus ( no ) , the value of the production of no by the time constant of fading ( tau ) , the value of proportion of the signal to the background ( no/nphi ) and , in addition , the value of the variation coefficient under the measurement of the rat liver tetraploid cells .
