Mag-Fura-2, Tetrasodium Salt Fluorescent Magnesium Indicator
Our Mag-Fura-2 Tetrasodium Salt is a fluorescent magnesium and calcium indicator that can be loaded into cells via microinjection or scrape loading. Calcium and magnesium imaging are widely used to measure neuronal activity.
Product Specifications
Background
Mag-Fura-2 is a UV-excitable fluorescent indicator for magnesium with a Kd 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 higher Kd 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.
