                                                                                                                     The COVID-19 caused by the new coronavirus (2019-nCoV) draws everyone's attention. The diagnosis of new coronavirus infection is an important part of the epidemic prevention and control. As a professional supplier of raw materials for in vitro diagnostic reagents, Cnpair always pays close attention to the development of the epidemic. After in-depth analysis of viral gene sequences and construction of specific protein sequences, Cnpair successfully developed a series of recombinant proteins for serological detection of 2019-nCoV. At present, Cnpair has successfully developed the COVID-19 (2019-nCoV) Nucleocapsid protein (N-protein) and (2019-nCoV) Spike protein (S-protein) recombinant proteins. Both proteins meet the needs of 2019-nCoV detection
