Mag-Fluo-4 Tetrapotassium Salt Fluorescent Magnesium Indicator
Our Mag-Fluo-4 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-Fluo-4 is a fluorescent ion indicator and analog of Fluo-4. The indicator has an affinity for magnesium (Kd = 4.7 mM) and low-affinity for calcium (Kd = 22 uM) with absorbance/emission at 493/517 nm (high Mg2+) . The cell membrane-impermeant tetrapotassium salt form can be introduced into cells by microinjection.
