Yellow-green fluorescent, sodium (Na+) indicator, membrane impermeable. Higher Na+ affinity than ING-1.

 

ION Natrium Green – 2 (ING-2) is a yellow-green fluorescent, intracellular sodium (Na+) indicator with improved cellular loading and significantly higher brightness than SBFI. Its spectral properties (Ex/Em: 525 nm/545 nm) and large dynamic range make ING-2 the best Na+ indicator for high-throughput screening applications targeting Na+ channels, and non-selective monovalent cation channels. ING-2 has a more physiologically relevant affinity (Kd = 20 mM) than ING-1 (Kd = 92 mM). Also compatible with fluorescence microscopy using common fluorescein, GFP or more ideally YFP filters.
 

ING-2 TMA+ salt is a membrane impermeable form of ING-2 that can be used in lipid membrane-free systems, in liposomes, or can be introduced
