Furaptra, Tetrasodium Salt

Description: Mag-Fura-2 is a UV-excitable fluorescent indicator for magnesium with a K_d of 1.9 mM. 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. Mag-Fura-2/tetrasodium salt can be loaded into cells by microinjection or scrape loading. Also see Mag-Fura-2, tetrapotassium salt and the cell membrane-permeant Mag-Fura-2 AM ester.
