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: Nucleocapsid (N) protein is the most abundant protein found in coronavirus. CoV N protein is a highly immunogenic phosphoprotein important for viral genome replication and modulation of cell signaling pathways. It was first identified by a research team while they were screening for ADP-ribosylated proteins during coronavirus (CoV) infection (Grunewald M. E., et al. 2017, Virology; 517: 62-68). The array of diverse functional activities accommodated in N protein makes it more than a structural protein but also an interesting target in the development of antiviral therapeutics. Because of the conservation of N protein sequence and its strong immunogenicity, N protein of coronavirus is chosen as a diagnostic tool.

Description: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is an enveloped, positive-sense, single-stranded RNA virus that causes coronavirus disease 2019 (COVID-19). Virus particles include the RNA genetic material and structural proteins needed for invasion of host cells. Once inside the cell the infecting RNA is used to encode structural proteins that make up virus particles, nonstructural proteins that direct virus assembly, transcription, replication and host control and accessory proteins whose function has not been determined. ORF3a encodes a viral accessory protein. Based on its similarity to other coronavirus proteins, ORF3a protein is thought to be a protein with ion channel activity (viroporin) that activates the NLRP3 inflammasome. ORF3a may also play a role in virus replication and pathogenesis.
