Methods are provided for detecting the binding of a first member to a second member of a ligand pair, comprising the steps of (a) combining a set of first tagged members with a biological sample which may contain one or more second members, under conditions, and for a time sufficient to permit binding of a first member to a second member, wherein said tag is correlative with a particular first member and detectable by non-fluorescent spectrometry, or potentiometry; (b) separating bound first and second members from unbound members; (c) cleaving the tag from the tagged first member; and (d) detecting the tag by non-fluorescent spectrometry, or potentiometry, and therefrom detecting the binding of the first member to the second member.
本发明提供了检测
配体对中第一成员与第二成员结合的方法,包括以下步骤:(a) 在足以允许第一成员与第二成员结合的条件和时间下,将一组第一标记成员与可能含有一个或多个第二成员的
生物样品结合,其中所述标记与特定的第一成员相关,并可通过非荧光光谱法或电位计法检测;(b) 将结合的第一和第二成员与未结合的成员分离; (c) 从标记的第一成员上裂解标记;以及 (d) 通过非荧光光谱法或电位测定法检测标记,并由此检测第一成员与第二成员的结合情况。
