Title:
FRUCTOSE-1,6-DIPHOSPHATE OPTICAL PROBE, AND PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/094002
Kind Code:
A1
Abstract:
The present invention relates to a fructose diphosphate optical probe. Specifically, provided in the present invention is a fructose diphosphate optical probe, which comprises a fructose-1,6-diphosphate sensitive polypeptide and an optically active polypeptide, wherein the optically active polypeptide is located within the sequence of a fructose-1,6-diphosphate sensitive polypeptide, the fructose-1,6-diphosphate sensitive polypeptide is a fructose-1,6-diphosphate binding protein or a functional variant thereof, and the optically active polypeptide is a fluorescent protein or a functional variant thereof. The fluorescent probe of the present invention has a large dynamic change in terms of fluorescence and a good specificity, and can be used for high-throughput and quantitative detection of fructose diphosphate inside and outside a cell.
