The present invention relates to a probe for iFRET and use thereof. Specifically, the present invention relates to a novel probe for iFRET, a method for preparing the probe for iFRET, a method for searching a target protein-specific binding site or a molecule having the binding site using the probe for iFRET, and a method for imaging the target protein using the probe for iFRET. The probe for iFRET according to the present invention utilizes an amino acid in a protein as a fluorescent donor, unlike the conventional FRET method. Therefore, only one fluorescent material is used, and its emission wavelength is distinct from the intrinsic fluorescence of the protein. Thus, high specificity and sensitivity are ensured, and the quantity, activity and mechanism of various proteins can be analyzed in an easy and accurate manner.
本发明涉及一种用于iFRET的探针及其使用。具体而言,本发明涉及一种新型iFRET探针、制备iFRET探针的方法、使用iFRET探针搜索靶蛋白特异性结合位点或具有结合位点的分子的方法,以及使用iFRET探针成像靶蛋白的方法。本发明的iFRET探针利用蛋白质中的氨基酸作为荧光给体,而不是传统的FRET方法。因此,仅使用一个荧光材料,其发射波长与蛋白质的内在荧光不同。因此,确保了高度的特异性和灵敏度,并且可以轻松准确地分析各种蛋白质的数量、活性和机制。
