FM4-64

CAS No. : 162112-35-8

產品活性：FM4-64 is a very lipophilic, water-soluble styrene dyes, can specifically bind to cell membranes and inner membrane organelles to produce fluorescence. FM4-64 is widely used in endocytic and exospic membrane structure markers. Storage: protect from light.

研究領域：Others

作用靶點：Fluorescent Dye

In Vitro: 1. Preparation of FM working solution
1.1 Preparation of the stock solution
Dissolve FM in DMSO to obtain 5 mM of FM.
Note: It is recommended to store the stock solution at -20℃?or -80℃?away from light and avoid repetitive freeze-thaw cycles.
1.2 Preparation of FM working solution
Dilute the stock solution in HBSS to obtain 5-20 μM of FM working solution.
Note: Please adjust the concentration of FM working solution according to the actual situation.
2. Cell staining
2.1 Suspension cells (6-well plate)
a. Centrifuge at 1000 g at 4℃?for 3-5 minutes and then discard the supernatant. Wash twice with PBS, 5 minutes each time.The cell density is 1×10⁶/mL
b. Add 1 mL of working solution, and then incubate at room temperature for 5-30 minutes.
c. Centrifuge at 400 g at 4℃?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 5-30 minutes.
d. Wash twice with medium, 5 minutes each time. Observation by fluorescence microscopy or flow cytometry.
Storage
-20℃,1 year.
Protect from light.
