Abstract: Provided is an isolated binding protein including an antigen binding domain binding to an NS1 protein, and comprising specific heavy chain CDR and light chain CDR. The binding protein can specifically identify and bind to NS1, and has relatively high sensitivity and specificity, so as to detect dengue virus. Moreover, the binding protein does not need to be produced by injecting hybridoma cells into mouse peritoneal cavity, while simplifying production, thus stabilizing antibody functionality.
