    • A two-photon probe for real-time monitoring of intracellular calcium ions is provided. The two-photon probe is very suitable for real-time imaging of intracellular calcium ions, shows 20-5 O-fold TPEF enhancement in response to Ca2+, has a dissociation constant (Kdτp) of 0.14±0.02 to 0.25±0.03 μM, and emits 5-fold stronger TPEF than currently available one-photon fluorescent Ca2+ probes. Unlike the previously available probes, the two-photon probe can selectively detect dynamic levels of intracellular free Ca2+ in live cells and living tissues without interference from other metal ions and from the membrane-bound probes. Moreover, the two-photon probe is capable of monitoring the calcium waves at a depth of 100-300 μm in live tissues for 1,100-4,000 s using two-photon microscopy (TPM) with no artifacts of photo-bleaching. Further provided are a method for preparing the two-photon probe and a method for real-time monitoring of intracellular calcium ions using the two-photon probe.
    • 提供了用于实时监测细胞内钙离子的双光子探针。 双光子探针非常适用于细胞内钙离子的实时成像,对Ca2 +响应显示20-5 O倍TPEF增强,解离常数(Kdτp)为0.14±0.02〜0.25±0.03μM, 比目前可用的单光子荧光Ca2 +探针发射5倍更强的TPEF。 与以前可用的探针不同,双光子探针可以选择性地检测活细胞和活组织中细胞内游离Ca 2+的动态水平,而不受其他金属离子和膜结合探针的干扰。 此外,双光子探针能够使用双光子显微镜(TPM)在活组织中监测1100-300μm深度的钙波,而不会产生光漂白。 还提供了制备双光子探针的方法和使用双光子探针实时监测细胞内钙离子的方法。
