Abstract

The invention discloses a SYBR GreenⅠReal-time PCR method for rapid detection and identification of Hantaan virus infection. The method mainly designs a pair of specific primers based on the sequence of the conserved region of the S gene in the GenBank database. The gradient diluted positive plasmid was used as the standard, the reaction conditions were optimized, and the specific amplification by qRT-PCR was used to establish the SYBR Green Ⅰ Real-time PCR method for the detection of Hantaan virus nucleic acid in infected Vero E6 cells, infected mice and clinical patients, and the detection sensitivity A copy number of 101 was reached and tested for sensitivity, reproducibility, and specificity. Compared with conventional Hantaan virus detection and identification methods, this method has the advantages of rich types of detection specimens, wide application range, strong contrast, few operation steps, convenient and fast, high sensitivity, high repeatability and specificity, and has good The advantage of a linear relationship. It provides a strong experimental basis for the clinical, laboratory detection and epidemiological research of hemorrhagic fever with renal syndrome.
