摘要： The present invention describes a family of fluorescent indicators for metal cations. The indicators are fluorophore conjugates of pyridyl-based metal ion chelators. The indicators are very sensitive detection as quantification reagents for a variety of metals, in a variety of oxidation states, even in the presence of high concentrations of Ca.sup.2+, Na.sup.+, or K.sup.+ or other ions, such as is found in seawater, making them highly useful for assaying physiological samples, biological samples, or environmental samples.
摘要翻译： 本发明描述了一系列用于金属阳离子的荧光指示剂。 指标是吡啶基金属离子螯合剂的荧光团缀合物。 这些指标作为各种金属的定量试剂，作为多种氧化态的定量试剂，即使在高浓度的Ca2 +，Na +或K +或其他离子存在下也是非常敏感的，例如在海水中发现，使其高度 可用于测定生理样品，生物样品或环境样品。
