Product nameION NaTRIUM Green™-2 TMA+ Salt, cytosolic Na+ indicator
DescriptionCell membrane impermeable cytosolic Na+ indicator. Water soluble.
ION NaTRIUM Green™-2 TMA+ Salt, cytosolic Na+ indicator is a visible wavelength fluorescent indicator with a useful dynamic range for measuring cytosolic Na+ concentrations. It loads readily into cells and is excited by visible light. Although ANG-1 excites maximally at 517nm, 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. It is available as the tetramethylammonium (TMA+) salt and the acetoxymethyl (AM) ester. The TMA+ salt form is
provided for patch-clamping and other direct methods of introducing the dye into cells, as well as for in vitro calibration of the
Storage instructionsStore at -20°C. Store under desiccating conditions. The product can be stored for up to 12 months.
Soluble in water
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
