Assay methods are provided or determining an analyte in a sample suspected of containing the analyte. The method is carried out using a composition that includes a conjugate of a first sbp member with a particle. A luminescer is reversibly associated with a nonaqueous phase of the particle. Where the first spb member is not complementary to the analyte, a second sbp member that is capable of binding to the first sbp member is employed. Unbound conjugate is separated from conjugate that is bound to the analyte or to the second sbp member. A reagent for enhancing the detectability of the luminescer is added and the light emission of the luminescer acted on by the reagent is measured.
本发明提供了测定疑似含有被分析物的样品中被分析物的方法。 该方法使用一种组合物,该组合物包括第一 sbp 成员与颗粒的共轭物。 发光剂与颗粒的非
水相可逆地结合。 如果第一 sbp 成员与被分析物不互补,则使用能够与第一 sbp 成员结合的第二 sbp 成员。 从与被分析物或第二 sbp 成员结合的共轭物中分离出未结合的共轭物。 添加用于提高发光剂可检测性的试剂,并测量发光剂在试剂作用下的光发射。
