Kit for detecting SARS-CoV-2 neutralizing antibody and preparation method thereof

The invention relates to the technical field of medical detection, in particular to a kit for detecting a SARS-CoV-2 neutralizing antibody and a preparation method thereof. According to the kit, the neutralizing antibody in a serum or plasma sample is detected by adopting a technical principle that an enzyme-labeled neutralizing antibody and an antibody in a to-be-detected sample are competitively combined with an S protein antigen. The invention provides a full-automatic high-throughput detection method based on the kit, the method is based on a full-automatic immunoassay instrument platform, rapid, quantitative, high-throughput and automatic detection of a SARS-CoV-2 neutralizing antibody can be realized, detection can be carried out in a clinical laboratory, a result can be reported within 20 minutes, and 200 samples can be detected per hour. 本发明涉及医学检测技术领域，尤其涉及一种检测新冠病毒中和抗体的试剂盒及其制备方法。该试剂盒采用酶标记的中和抗体与待测样本中的抗体竞争结合S蛋白抗原的技术原理检测血清或血浆样本中的中和抗体。基于该试剂盒本发明提供一种全自动高通量的检测方法，该方法基于全自动免疫分析仪器平台，可实现新冠病毒中和抗体的快速、定量、高通量、自动化检测，可在
