Antibodies for Detecting SARS-CoV-2

Ending the COVID-19 pandemic and controlling the spread of SARS-CoV-2 infection requires having diagnostic tools that can accurately detect the virus, as well as therapies that can treat COVID-19, and perhaps, prevent viral infection. To help develop these tools, R&D systems offers antibodies that can be used for a variety of applications including identifying those cells susceptible to SARS-CoV-2 infection or assessing assay performance during development.

Antibodies for Investigating Viral Recognition by SARS-CoV-2

A key mechanism of SARS-CoV-2 infection is the binding of the coronavirus to the cell surface receptor ACE-2. This important step in viral recognition is a major target for therapeutic development. R&D Systems offers antibodies directed against virus and host cell molecules involved in viral infection, such as ACE-2 and SARS-CoV-2 proteins, that can be used to characterize protein expression or as a control for assessing the effectiveness of newly developed therapeutics.

Blocking Antibodies for SARS-CoV-2, ACE-2 and More

A major step in developing therapeutics to block SARS-CoV-2 infection involves determining the neutralization efficacy of the potential biologics or small molecules. R&D Systems offers a selection of blocking antibodies directed against SARS-CoV-2, ACE-2, and other viral and host cell antigens that can be used as controls in SARS-CoV-2 blocking/neutralization assays.

Antibodies for SARS-CoV-2 Immunoassay Development

Health experts have called for the broad screening of individuals for SARS-CoV-2 infection in order to help control the spread of this virus. However, the diagnostic tests currently used have several limitations, making them less than ideal for mass testing. There is a need to develop tests that are quick to run and easy to use, such as Lateral Flow Immunoassays (LFIAs). R&D Systems offers high-affinity SARS-CoV-2 antibodies for immunoassay development.

Antibodies for Characterizing SARS-CoV-2-Induced Immune Responses

The immunopathogenesis of SARS-CoV-2 infection continues to be a major focus of COVID-19 research as defining the contributions of immune responses in COVID-19 disease progression and severity is necessary to advance the development of therapies that regulate dysfunctional immune responses. R&D Systems offers antibodies for characterizing immune responses induced by SARS-CoV-2 infection.

Key SARS-CoV-2 Citations Utilizing R&D Systems Antibodies

Since publication of the pivotal papers at the beginning of 2020 by Zhou, J. et al.and Hoffmann, M. et al., which used our ACE-2 antibody to show that SARS-CoV-2 uses this cell surface receptor to infect cells, our antibodies have been used in a broad range of COVID-19 research. Explore these key SARS-CoV-2 and COVID-19 related citations to see how our antibodies are being used to advance COVID-19 research.

Publication Spotlight

A newly released preprint study suggested that investigation of ACE-2 protein expression has been lacking due to the unreliable specificity of most commercial ACE-2 antibodies. Authors of the study independently validated 13 ACE-2 antibodies for flow detection of ACE-2 to study cellular heterogeneity of its expression. The authors determined that of the 13 antibodies tested, only two, R&D Systems Goat Anti-Human/Mouse/Rat/Hamster ACE-2 Antigen Affinity-Purified Polyclonal Antibody (Catalog # AF933) and Mouse Anti-Human/Rat/Hamster ACE-2 Monoclonal Antibody (Catalog # MAB9332), showed specific ACE-2 detection. The other 11 antibodies did not exhibit any staining above background or had staining that was not affected by ACE-2 overexpression or deletion.
