With the now global outbreak of the novel SARS-like coronavirus, SARS-CoV-2 (2019-nCoV, COVID-19 virus) early diagnostics and infection prevention and control has become critical. Early detection leading to quarantine can significantly impact the ability of local governments to limit rapid spread to at risk patients. Scientists identified the novel coronavirus as a group 2B CoV, distinct from the SARS-CoV [1-3]. Genome sequencing indicated that SARS-CoV-2 (2019-nCoV) shares 79.5% sequence identity with SARS-CoV and 96% of identity with a bat coronavirus .
RayBiotech now offers the following COVID-19 related product lines:
The the rapid assay listed below is for in vitro diagnostic use, following guidance from the FDA for Emergency Use Authorizations of tests submitted for approval on March 16, 2020. The tests have not been reviewed by the FDA and results from antibody testing should not be used as the sole basis to diagnose or exclude SARS-CoV-2 (COVID-19) infection or to inform infection status.
RayBiotech offers lateral flow devices for the detection of IgG and IgM antibodies to the coronavirus N-protein in serum, plasma, and peripheral blood. An example of a lateral flow device is a home pregnancy test. They are easy to use and provide rapid results.
RayBiotech offers a variety of tools used to help understand and accelerate the COVID-19 research and detection. To help researchers quickly identify relevant products, we’ve listed confirmed detection kits, proteins, and antibodies against the virus, as well as related cytokine detection products that could be of use for human coronavirus research.
20 tests. Suitable for the qualitative detection of new coronavirus (SARS-CoV-2 / COVID-19) nucleocapsid protein N gene in human throat swabs and alveolar lavage. Includes a one-step RT-qPCR mix. Conforms to CDC guidelines. LDT ready for high complexity CLIA labs.
The spike protein (S-protein) and nucleocapsid protein (N-protein) are encoded by all coronaviruses, including the coronavirus (COVID-19) that was first detected in Wuhan City, China, in December 2019. Both recombinant forms of these proteins are now available from RayBiotech to advance infectious disease research.
COVID-19 N-Protein ELISA Kit. The nucleocapsid protein (N-protein) is a structural protein that binds to the coronavirus RNA genome, thus creating a shell (or capsid) around the enclosed nucleic acid.
Human ACE-2 (angiotensin-converting enzyme 2) is a zinc metalloproteinase responsible for the conversion of angiotensin I to angiotensin 1-9, and angiotensin II to angiotensin 1-7. The ACE2 gene is expressed in a variety of cell and tissue types, including the lung alveolar epithelium where it is thought to exert protective effects during acute lung injury. ACE-2 protein can be secreted but is also present as an integral membrane protein that serves as the initial attachment point for SARS-CoV and SARS-CoV-2 [5,6]. All coronavirus strains have a spike protein (S-protein) that mediates viral entry into the cell via interaction with ACE-2. Soluble ACE-2 has been shown to block the binding of SARS-CoV S-protein, potentially slowing down viral replication .

During infection of the coronavirus COVID-19, high levels of inflammatory cytokines have been reported. These cytokines include interferons, interleukins, chemokines, colony-stimulating factors, and tumor necrosis factors and contribute to the symptoms of coronavirus infection: redness, swelling/edema, fever, and pain. Overproduction of pro-inflammatory cytokines can result in a “cytokine storm,” during which inflammation spreads throughout the body via the circulation. One common consequence of a cytokine storm is acute lung injury, which can progress to a more severe form called acute respiratory distress syndrome. The dynamic relationship of cytokines during inflammation can be measured using RayBiotech’s quantitative inflammation antibody arrays below. These Quantibody® arrays are a multiplex ELISA platform suitable for all liquid sample types, providing quantitative data (i.e., concentrations) of your proteins-of-interest .
