RhoNox-1
Based on 45 publication(s) in Google Scholar
RhoNox-1 is a fluorescent probe for the specific detection of divalent iron ions, and when RhoNox-1 reacts with Fe2+. RhoNox-1 can generate an irreversible orange (red) fluorescent product (Ex/Em:540/575 nm) . FeRhoNox-1 can enter the cell well, suitable for the detection of Fe2+ in living cells, and tends to be localized in the Golgi apparatus.

Guidelines (Following is our recommended protocol. This protocol only provides a guideline, and should be modified according to your specific needs).
1. Preparation of RhoNox-1 working solution
1.1 Preparation of the stock solution
Dissolve RhoNox-1 in DMSO to obtain 1 mM of stock solution.
1.2 Preparation of RhoNox-1 working solution
Dilute the stock solution in serum-free cell culture medium or PBS to obtain 1-10 μM of working solution.
Note: Please adjust the concentration of RhoNox-1 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 5-30 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 5-30 minutes.
3.4 Wash twice with medium, 5 minutes each time. Observation by fluorescence microscopy.
