Sample solution is provided at 25 µL, 10mM.
Caged calcium (Kd values are 48 and 19 nM at pH 7.2 and 7.4, respectively; Kd after uncaging = 2 mM). Selective over Mg2+ (Kd =10 mM). Rapid and efficient calcium release upon photolysis at 350 nm. Can also be used for two-photon uncaging. Extinction coefficient of 5120 M-1 cm-1, quantum yield 0.09. Cell permeable.
