  • Description
  • References
  • Mag-Fura-2 is a UV-excitable fluorescent indicator for magnesium with a Kd of 1.9 mM.1,2 Similar to Fura-2, the excitation wavelength of Mag-Fura-2 undergoes a blue shift from 369 nm to 330 nm. Mag-Fura-2 also responds to Ca2+ but with a significantly lower Kd than Fura-2 to Ca2+. An important application of Mag-Fura-2 is its use in detecting high, transient Ca2+ concentration during Ca2+ spikes.3,4 Mag-Fura-2/tetraammonium salt can be loaded into cells by microinjection or scrape loading.

    Light yellow solid soluble in water (pH > 6). Store at -20°C and protect from light.
