SARS-CoV-2 Recombinant Proteins

SARS-CoV-2 is an enveloped positive-strand RNA virus that consists of four structural proteins: spike (S) protein, envelope (E) protein, membrane (M) protein and nucleocapsid (N) protein. The spike protein is the most important surface protein of coronavirus. It mediates the entry of SARS-CoV-2 into human respiratory epithelial cells by interacting with the cell surface receptor angiotensin-converting enzyme 2 (ACE2).
BioCat provides a large selection of recombinant proteins for SARS-CoV-2 research including spike protein, spike protein mutants, nucleocapsid protein and angiotensin-converting enzyme 2, see link below.

SARS-CoV-2 Recombinant Proteins

SARS-CoV-2 Protein & Antibody Detection by ELISA

Current testing for the SARS-CoV-2 virus is limited, and compared to RT-qPCR, ELISA is a less complex procedure that uses more affordable and available equipment. Similarly, antigens and antibodies are considerably more stable than RNA, which reduces the potential of false-negative results. The ability to collect samples from many places in the body (and not restricted to nasal swabs) improves testing accuracy as well. For the measurement of human IgG, IgM or IgA antibodies against SARS-CoV-2 N-protein or SARS-CoV-2 S-protein (S1 RBD) in human serum, plasma, saliva or dried blood samples, we offer indirect ELISAs. In addition, sandwich-based ELISAs measuring SARS-CoV-2 antigens like S- or N-protein are provided.


SARS-CoV-2 IgM and IgG Antibody Detection using Peptide Microarrays

In light of the recent coronavirus disease (COVID-19) outbreak, our partner RayBio has developed a peptide microarray based on the SARS-CoV-2 spike protein. It is designed for the semi-quantitative detection of IgM and IgG antibodies specific for SARS-CoV-2 spike (S) protein in serum or plasma.

RayBio Inflammation Cytokine Arrays & ELISA Kits

During infection of the coronavirus SARS-CoV-2, 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.

Using quantitative inflammation antibody arrays developed by our partner RayBio, the dynamic relationship of cytokines during inflammation can be measured.

Specific inflammatory proteins can be measured with RayBio ELISA kits. Below are some of the featured ELISA kits to help study COVID-19 inflammation:

If the ELISA kit you are looking for is not listed here, e.g. ACE2 ELISA Kits, please use our ELISA Search Tool

SARS-CoV-2 Spike Protein-Pseudotyped Lentivirus

SARS-CoV-2 (2019-nCoV) Background

There are four coronavirus genera [ii]: alphacoronavirus, betacoronavirus, gammacoronavirus, and deltacoronavirus. SARS-CoV-2 (2019-nCoV) belongs to the Betacoronavirus genus originating from bats. Betacoronaviruses can infect mammals, are zoonotic pathogens, and can cause severe respiratory disease in humans. Other viruses in this family are SARS coronavirus and MERS coronavirus. SARS-CoV-2 (2019-nCoV) has approximately 79% sequence identity to SARS-CoV and 50% to MERS-CoV [iii]. In addition, homology modeling shows SARS-CoV-2 (2019-nCoV) has a similar receptor-binding domain structure as SARS-CoV which suggests SARS-CoV-2 (2019-nCoV) may use ACE2 as a receptor in humans for infection.

SARS-CoV-2 (2019-nCoV) Structure

The structure [iv] of SARS-CoV-2 (2019-nCoV) consists of the following: a spike protein (S), hemagglutinin-esterease dimer (HE), a membrane glycoprotein (M), an envelope protein (E) a nucleocapsid protein (N) and RNA as seen in the figure.
