HOE 32021
Based on 1 Customer Validation
HOE 32021 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.

Guide (Following is our recommended protocol. This protocol only provides a guideline, and should be modified according to your specific needs).
1. Preparation of HOE 32021 working solution
1.1 Preparation of the stock solution
Dissolve Hoechst in DMSO to obtain 1 mg/mL HOE 32021 stock solution
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 HOE 32021 working solution.
Note: Please adjust the concentration of HOE 32021 working solution according to the actual situation.
2. Cell staining (Suspension cells)
2.1 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 1×106/mL.
2.2 Add 1 mL of working solution, and then incubate at room temperature for 3-10 minutes.
2.3 Centrifuge at 400 g at 4°C for 3-4 minutes and then discard the supernatant.
2.4 Wash twice with PBS, 5 minutes each time.
2.5 Resuspend cells with serum-free cell culture medium or PBS. Observation by fluorescence microscopy or flow cytometry.
3. Cell staining (Adherent cells)
3.1 Culture adherent cells on sterile coverslips.
3.2 Remove the coverslip from the medium and aspirate excess medium.
3.3 Add 100 μL of working solution, gently shake it to completely cover the cells, and then incubate at room temperature for 3-10 minutes.
3.4 Wash twice with medium, 5 minutes each time. Observation by fluorescence microscopy or flow cytometry.
