Asante NaTRIUM Green-1

Asante NaTRIUM Green 1 is a visible wavelength fluorescent indicator with a useful dynamic range for measuring cytosolic Na+ concentrations. Unlike SBFI, it loads readily into cells and is excited by visible light. Although ANG-1 excites maximally at 517 nm, its exceptional brightness enables excitation at the standard 488 nm settings used for the Fluo calcium indicators. Moreover, it works well for 2-photon excitation with near-infrared light. ANG-1 is also remarkable in its resistance to photobleaching and leakage.
