A nonlinear optical technique, such as second or third harmonic or sum or difference frequency generation, is used to detect binding interactions, or the degree or extent of binding, that comprise a conformational change. In one aspect of the present invention, the nonlinear optical technique detects a conformational change in a probe due to target binding. In another aspect of the invention, the nonlinear optical technique screens candidate probes by detecting a conformational change due to a probe-target interaction. In another aspect of the invention, the nonlinear optical technique screens candidate modulators of a probe-target interaction by detecting a conformational change in the presence of the modulator.
非线性光学技术,如二次或三次谐波或总频或差频发生技术,可用于检测包含构象变化的结合相互作用或结合程度或范围。在本发明的一个方面,非线性光学技术可检测探针因目标结合而发生的构象变化。在本发明的另一方面,非线性光学技术通过检测探针与目标相互作用引起的构象变化来筛选候选探针。在本发明的另一方面,非线性光学技术通过检测存在调制器时的构象变化来筛选探针与目标相互作用的候选调制器。
