The traditional Chinese medicine has cure effect of the diseases such as dengue, Zika virus, encephalitis, hepatitis and liver cancer infected by flaviviridae spreading, can treat and repair the blood cell from the source, has prophylaxis and treatment effect on flaviviridae diseases, is without any toxicity and side effects, and can improve the cure rate and cure efficiency of patients.

A kit and special alkali inducers for amplification and probes can be used to check out dengue fever virus. The inducers consist of a couple of opposite directions. One is of sequence shown in No.1, another is of sequence shown in No.2, and probes shown in No.3. The process has advantages, e.g. quick action, simple, high sensitivity and specification in detection of dengue fever virus I, II, III and IV.

The invention relates to the technical field of biological detection, and in particular relates to a primer, a probe and a kit used for detecting dengue fever, chikungunya and yellow fever virus through a single tube by the multiplex-fluorescence PCR (Polymerase Chain Reaction). The primer and probe used for detecting the dengue fever, chikungunya and yellow fever virus through the multiplex-fluorescence PCR have nucleotide sequences as shown in SEQ ID NO: 1-9; the multiplex PCR detection kit for detecting the dengue fever, chikungunya and yellow fever virus comprises multiplex-fluorescence PCR detection mixed liquid which contains the primer and probe mentioned above. The kit, primer and probe can quickly detect the dengue fever virus, chikungunya virus and yellow fever virus, have the advantages of being simple and convenient to operate, high in sensitivity and outstanding in specificity, and can timely find out and confirm a suspect case so as to improve the monitoring level on such diseases.

The invention provides an isolated binding protein having an antigen binding structural domain which is bound with NS1 protein. The isolated binding protein comprises specific heavy chain CDR and light chain CDR, can recognize and bind with the NS1 protein specifically, has high flexibility and specificity, and can realize detection on dengue fever virus. The way of utilizing mouse peritoneal induced hybridoma to produce the binding protein is omitted, and thus, production difficulty of the binding protein is reduced while antibody function thereof is much stable.
