C11 BODIPY 581/591

This plan only provides a guide, please modify it to meet your specific needs.
1. Preparation of staining solution
(1) Prepare storage solution: Dissolve C11 BODIPY 581/591 in DMSO and prepare a storage solution with a concentration of 1-10mM.
Note: Unused storage solution should be aliquoted and stored in the dark at -20°C or -80°C to avoid repeated freezing and thawing.
(2) Prepare working solution: Dilute the storage solution with a suitable buffer (such as serum-free medium or PBS) and prepare a working solution with a concentration of 1-10μM.
Note: Please adjust the concentration of the working fluid according to the actual situation and prepare it now.

2. Cell suspension staining
(1) Suspension cells: Centrifuge at 1000g for 3-5 minutes at 4°C, discard the supernatant, and wash twice with PBS for 5 minutes each time.
(2) Adherent cells: Wash twice with PBS, add trypsin to digest the cells, and centrifuge at 1000g for 3-5 minutes after digestion is completed.
(3) Add 1 mL of C11 BODIPY 581/591 working solution to resuspend the cells, and incubate at 37 °C in the dark for 5-30 minutes. The optimal incubation time for different cells is different, please explore by yourself according to the specific experimental needs.
(4) After the incubation, centrifuge at 1000g for 5 minutes, remove the supernatant, add PBS and wash 2-3 times, 5 minutes each time.
(5) Resuspend cells in pre-warmed serum-free cell culture medium or PBS and observe by fluorescence microscope or flow cytometry.

3. Cell adhesion staining
(1) Culture adherent cells on sterile coverslips.
(2) Remove the coverslip from the culture medium, suck out the excess culture medium, and place the coverslip in a humid environment.
(3) Add 100 μL of dye working solution from one corner of the coverslip and shake gently to evenly cover all cells with the dye.
(4) Incubate at 37 °C in the dark for 5-30 minutes. The optimal incubation time for different cells is different, please explore by yourself according to the specific experimental needs.
(5) After the incubation, discard the dye working solution and use pre-warmed culture solution to wash the coverslip 2 to 3 times.
4. Microscope detection: The excitation light and emission light of the oxidized form of C11 BODIPY 581/591 are 460-495nm and 510-550nm respectively; the excitation light and emission light of the reduced form are 565-581nm and 585-591nm respectively.
Precautions:
1) Fluorescent dyes all have quenching problems. Please avoid light as much as possible to slow down fluorescence quenching.
2) For your safety and health, please wear a lab coat and disposable gloves.
