1.1 Preparation of the stock solution<\/strong><\/span>
\nDissolve 10 mg of in 5 mL ddH2<\/sub>O
\nNote: It is recommended to store the stock solution at 4\u00b0C or -20\u00b0C away from light and avoid repetitive freeze-thaw cycles.<\/p>\n

1.2 Preparation of Hoechst working solution<\/span><\/strong>
\nDilute the stock solution in serum-free cell culture medium or PBS to obtain final concentration 10 \u03bcg\/mL Hoechst working solution.
\nNote: Please adjust the concentration of Hoechst working solution according to the actual situation.
\n1.Cell staining
\n2.1 Suspension cells\uff086-well plate\uff09<\/strong><\/span>
\na. Centrifuge at 1000 g at 4\u00b0C for 3-5 minutes and then discard the supernatant. Wash twice with PBS, 5 minutes each time.The cell density is 1\u00d7106<\/sup>\/mL.
\nb. Add 1 mL of working solution, and then incubate at room temperature for 3-10 minutes.
\nc. Centrifuge at 400 g at 4\u00b0C for 3-4 minutes and then discard the supernatant.
\nd. Wash twice with PBS, 5 minutes each time.
\ne. Resuspend cells with serum-free cell culture medium or PBS. Observation by fluorescence microscopy or flow cytometry.
\n2.2 Adherent cells<\/strong><\/span>
\na. Culture adherent cells on sterile coverslips.
\nb. Remove the coverslip from the medium and aspirate excess medium.
\nc. Add 100 \u03bcL of working solution, gently shake it to completely cover the cells,and then incubate at room temperature for 3-10 minutes.
\nd. Wash twice with medium, 5 minutes each time.Observation by fluorescence microscopy or flow cytometry.<\/p>\n
