Katalog No : 50035

Product Description

Mag-Fura-2 is a UV-excitable fluorescent indicator for magnesium with a K_d 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 K_d than Fura-2 for 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.
