A preliminary response of Asante Natrium Green-2 with sodium channel receptor, Nav 1.3 expressed in HEK 293 cells is shown in Figure 1 below. The wavelength of excitation used was 488 nm. Figure 2 shows various excitation wavelengths including emission maxima 517 nm. Filters or Flexstation may be neccessary for maximum response.

Rhod-2, with fluorescence excitation maxima at 552 nm and emission maxima at 581 nm, was first introduced in 1989. Rhod-2 is essentially non-fluorescent before Ca2+ binding, becoming more fluorescent with increasing Ca2+ concentration. The longer excitations and emissions of Rhod-2 make the indicator useful for experiments in cells and tissues that have high levels of autofluorescence... Read More
