Fluorescent intensity assay for protein or peptide binding to nucleic acids |
摘要 |
A method for assaying binding between a fluorophore-labeled compound and an unlabeled compound is provided. The method includes detecting a quenching effect on fluorescence emitted by the fluorophore-labeled compound resulting from binding. The binding is specific and other than nucleobase to nucleobase. The method is conducted without separating complexes of the fluorophore-labeled compound and the unlabeled compound from the fluorophore-labeled compound prior to quenching effect detecting, and without providing a signal quenching agent to quench fluorescent light. Preferably, the fluorophore-labeled compound is a nucleic acid and the unlabeled compound is a protein. The method can be used for a variety of applications, including screening for drug candidates having optimum binding properties, and quantifying the binding affinity of DNA binding proteins for nucleic acids. |
