Hoechst 33258 analog 5 is a marker dye in Hoechst series. Hoechst is A live nuclear marker dye. Hoechst binds to the grooves in the DNA double strand, which tends to be A/ T-rich DNA strand. Although it binds to all nucleic acids, the A/ T-rich double strand DNA significantly enhances fluorescence intensity Therefore,Hoechst dye can be used for living cell labeling. The fluorescence intensity of Hoechst dye increases with the increase of pH of solution.

General Protocol Preparation of Hoechst working solution 1.1 Preparation of the stock solution Dissolve 10 mg of in 5 mL ddH 2 O Note: It is recommended to store the stock solution at 4°C or -20°C away from light and avoid repetitive freeze-thaw cycles. 1.2 Preparation of Hoechst working solution Dilute the stock solution in serum-free cell culture medium or PBS to obtain final concentration 10 μg/mL Hoechst working solution. Note: Please adjust the concentration of Hoechst working solution according to the actual situation. 1.Cell staining 2.1 Suspension cells（6-well plate） a. Centrifuge at 1000 g at 4°C for 3-5 minutes and then discard the supernatant. Wash twice with PBS, 5 minutes each time.The cell density is 1×10 6 /mL. b. Add 1 mL of working solution, and then incubate at room temperature for 3-10 minutes. c. Centrifuge at 400 g at 4°C for 3-4 minutes and then discard the supernatant. d. Wash twice with PBS, 5 minutes each time. e. Resuspend cells with serum-free cell culture medium or PBS. Observation by fluorescence microscopy or flow cytometry. 2.2 Adherent cells a. Culture adherent cells on sterile coverslips. b. Remove the coverslip from the medium and aspirate excess medium. c. Add 100 μL of working solution, gently shake it to completely cover the cells,and then incubate at room temperature for 3-10 minutes. d. Wash twice with medium, 5 minutes each time.Observation by fluorescence microscopy or flow cytometry. Storage 4°C, 1 year. Protect from light Precautions 1. Please adjust the concentration of Hoechst working solution according to the actual situation. 2. This product is for R&D use only, not for drug, household, or other uses. 3. For your safety and health, please wear a lab coat and disposable gloves to operate. MCE has not independently confirmed the accuracy of these methods. They are for reference only.
