Novel coronavirus antigen colloidal gold diagnostic kit

The invention discloses an SARS-COV2 fibrin antibody which is a pairing antibody of an S1 region of SARS-COV2 fibrin. The invention further discloses a preparation method of the SARS-COV2 fibrin antibody. The preparation method of the SARS-COV2 fibrin antibody comprises the following steps: expressing and purifying a gene of an S1 protein Gln14-Arg685 region based on SARS-COV2 to obtain a fusion protein, and then preparing a paired antibody from the fusion protein. The SARS-COV2 fibrin antibody is used for preparing a novel coronavirus detection kit, and the invention provides the novel coronavirus antigen colloidal gold diagnosis kit which comprises the SARS-COV2 fibrin antibody. The SARS-COV2 colloidal gold diagnostic kit provided by the invention is simple to operate, can quickly diagnose whether a patient is infected with SARS-COV2 or not, and is beneficial to effective control of epidemic situations. 本发明公开了一种SARS-COV2纤突蛋白抗体，为SARS-COV2纤突蛋白S1区的配对抗体。SARS-COV2纤突蛋白抗体的制备方法，是基于SARS-COV2的S1蛋白Gln14-Arg685区域的基因，进行
