Flow Cytometric AnalysisPrior to flow cytometric analysis, the vital dye Hoechst 33342 (Sigma-Aldrich, St. Louis, MO, USA) was added to cell suspensions to a final concentration of 5 μg/mL and incubated for 10 min at 37°C in the dark. Cells were analyzed by means of a MoFlo Cytometer (DakoCytomation) equipped with a UV excitation wavelength laser (Innova 90C-6) operating at 25 mW and a 70-μm nozzle.Ana......阅读全文
