The invention provides dyes, biosensors, and methods for using the dyes and biosensors to detect selected target molecules. The biosensors have a binding domain and a dye, or a dye which is attached directly to the target of interest. Binding domains contemplated by the invention include biomolecules or fragments of biomolecules that interact with target molecules of interest and can be specific to a given conformational state or covalent modification of the molecule (e.g. phosphorylation). In one embodiment, the binding domain of a biosensor is a single chain variable fragment (scFv) with a dye of the invention linked to a CDR3 region. The invention also provides environmentally sensitive dyes useful for detecting changes in the binding, conformational change, or posttranslational modification of the selected target.
本发明提供染料、生物传感器及其使用方法,用于检测选定的目标分子。生物传感器具有结合域和染料,或者染料直接附着于感兴趣的目标上。本发明考虑的结合域包括与目标分子相互作用的生物分子或生物分子片段,可以特异性地针对分子的给定构象状态或共价修饰(例如磷酸化)。在一种实施方式中,生物传感器的结合域是单链可变片段(scFv),具有本发明的染料链接到CDR3区域。本发明还提供对环境敏感的染料,用于检测选定目标的结合、构象变化或翻译后修饰的变化。
