Description: The Anti-SARS-CoV-2 Neutralization Antibody Test Kit (Serum/Plasma/Whole blood) is a qualitative membrane-based immunoassay for the detection of SARS-CoV-2 neutralizing antibodies in serum, plasma and whole blood. The sample is dropped into the sample well, and chromatography is performed under the capillary effect. The SARS-CoV-2 neutralizing antibodies in the sample combined with the colloidal gold-labeled SARS-CoV-2 spike protein(SP), then spread to the test area. It is captured by coated SP subunit RBDNTD-CTD, to form a complex and gather in the test area (T line). The quality control area is coated with mouse anti-chicken IgY, and the colloidal goldlabeled chicken IgY is captureed to form a complex and aggregate in hte quality control area (C line). If the C line does not show color, it indicates that the result is invalid, and this sample need to be tested again.

Description: It is a semi quantitative competition ELISA kit to detect the Anti-SARS-CoV-2 Neutralization Antibody in human serum or plasma. The micro test plate provided in this kit is pre-coated with recombinant human ACE2. During the reaction, the SARS-CoV-2 neutralization antibody in the standard & sample diluent pretreated samples or controls competes with a fixed amount of human ACE2 on the solid phase supporter for sites on the Horseradish peroxidase (HRP) conjugated recombinant SARS-CoV-2 RBD fragment (HRP-RBD). After 37℃incubation, the unbound HRP-RBD as well as any HRP-RBD bound to non-neutralization antibody will be captured on the plate and eventually form the ACE2-RBD-HRP complex, while the circulating neutralization antibodies HRP-RBD complexes remain in the supernatant and are removed during washing. Then a TMB substrate solution is added to each well. The enzyme-substrate reaction is terminated by the addition of stop solution and the color change is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm.

Description: A rapid test for detection of antibodies (IgG and IgM) for 2019-nCoV, the novel Coronavirus from the Wuhan strain. The test is easy to perform, takes 10 minutes to provide reliable results and is higly specific to the 2019-nCoV Coronavirus.
