The present invention provides a fluorescence assay by introducing a rare earth metal cryptate measurement medium, which is less sensitive to fluorescence quenching, containing at least one pyridine group, which is substituted or unsubstituted one or more times. A method for reducing fluorescence quenching caused by a measurement medium. The invention also relates to novel rare earth metal cryptates which are less sensitive to fluorescence quenching caused by the measurement medium.
本发明提供了一种荧光测定方法,通过引入一种稀土
金属隐形测量介质,该介质对荧光猝灭的敏感性较低,含有至少一个
吡啶基团,该基团被取代或未取代一次或多次。一种用于减少由测量介质引起的荧光猝灭的方法。该发明还涉及一种新型稀土
金属隐形,其对由测量介质引起的荧光猝灭的敏感性较低。
