Biochem/physiol Actions
MagZet1 is a Mg2+ fluorescent sensor for the ratiometric detection of Mg2+ with good selectivity over Ca2+ (Kd = 140 µM/Mg2+ vs. 1.7 mM/Ca2+). At pH 7, MagZet1 shows Ex max/Em max/Φ of 490 nm/500 nm/40% in Mg2+-free and 395 nm/530 nm/76% in Mg2+-saturated form. Note: MagZet1 exhibits high affinity for Zn2+ (Kd = 2.6 nM), which is not expected to interfere with Mg2+ detection due to the typical low basal Zn2+ concentrations in cells (0.01 - 0.1 nM). Care should be taken, however, when the sensor is to be employed in Zn2+-rich samples. For detection: 405 nm excitation laser, emission 470-520 nm for the Mg2+-free form and 520-582 nm for the Mg2+-bound sensor.
