Fe2Orange 

Fe2Orange is a Fe²⁺ selective probe with an excitation wavelength of 543 nm and an emission wavelength of 580 nm. Fe2Orange emits fluorescence after binding to intracellular Fe²⁺, thereby achieving specific labeling of Fe²⁺. Fe2Orange is used to detect the content and distribution of Fe²⁺ in cells^[1].

Guide (The following is our recommended protocol. This protocol is only a guide and should be modified according to your specific needs).
1. Solution preparation
1.1 Preparation of stock solution
Solvent: DMSO
Concentration: 1 mM
1.2 Preparation of working solution
Dilute to 1 μM with HBSS or cell culture medium (optimized according to the experiment).
Note: The working solution should be prepared and used immediately. Keep it away from light.

2. Cell staining
2.1 Cells are plated in 96-well microplates.
2.2 Discard the cell culture medium and wash the cells three times with HBSS or serum-free medium.
2.3 Add the 1 μM FerroOrange working solution and incubate for 30 minutes at 37°C
2.4 Using fluorescence microscopy at Ex/Em = 540/585 nm.
