Methods and materials for scintillation assays are disclosed. The scintillation assays rely on differences in general molecular property-based binding interactions, such as charge or hydrophobicity, to localize a radioactive substance near a scintillating material, stimulating scintillation. They are thus described as a direct adsorption scintillation assay (DASA) to distinguish them from the scintillation proximity assay (SPA). The assays are more convenient and inexpensive to implement than SPAs, which rely on specific binding of ligand-receptor pairs, antibody-antigen pairs, or other binding partners which rely on the precise and specific structural complementarity of the partners. The assays can be employed for studying enzymatic reactions, such as those involved in the synthesis of Mur-pentapeptide. The assays are readily adaptable to high throughput screening for use in conjunction with combinatorial libraries of compounds.
本文公开了闪烁检测的方法和材料。闪烁检测法依靠基于一般分子特性的结合相互作用(如电荷或疏
水性)的差异,将放射性物质定位在闪烁材料附近,从而激发闪烁。因此,它们被称为直接吸附闪烁检测法(
DASA),以区别于闪烁邻近检测法(
SPA)。与
SPA 相比,直接吸附闪烁检测法更方便、成本更低,因为
SPA 依赖于
配体-受体对、
抗体-抗原对或其他结合伙伴的特异性结合,而
配体-受体对、
抗体-抗原对或其他结合伙伴的特异性结合则依赖于结合伙伴精确而特异的结构互补性。这些检测方法可用于研究酶促反应,如参与 Mur 五肽合成的酶促反应。这些检测方法可随时用于高通量筛选,与组合化合物库结合使用。
