Abstract
Flow cytometric analysis of the cell cycle is most effectively accomplished with membrane-/cytoplasma-free (clean) nuclei. Non-ionic detergents (e.g. NP40 or Triton X-100) commonly are employed to solubilize cells membranes/cytoplasm to produce 'clean' nuclei. Treatment of murine erythroleukemic cells with tri-n-butylin methoxide, cadmium acetate, zinc sulfate, or lead acetate alters the properties of the cell membrane/cytoplasm complex making it resistant to NP40 dissolution. On a molar basis, the organotin compound was more effective in inducing resistance to detergent-mediated dissolution than the inorganic metal compounds. Resistance to NO40-mediated dissolution was manifested as an increase in the flow cytometric parameters 90 degree scatter and fluorescein isothiocyanate fluorescence and was confirmed by light microscopy.
