COVID-19 Monoclonal & Polyclonal Antibodies

SARS-CoV-2 Antibodies for Research

RayBiotech offers monoclonal and polyclonal antibodies to SARS-CoV-2 (COVID-19) proteins, including the Spike protein (S1 subunit, receptor binding domain, S2 subunit) and Nucleocapsid protein (N-protein). Mouse monoclonal antibodies to the human Angiotensin-Converting Enzyme 2 (ACE2) receptor are also available.

Antibodies bind to specific sequences of amino acids, which are typically 5 - 8 residues in length. These sequences are known as "epitopes." Monoclonal antibodies bind to one epitope whereas polyclonal antibodies bind to multiple epitopes. This major difference is because each monoclonal antibody is derived from one hybridoma cell line whereas each polyclonal antibody is actually a pool of antibodies that are produced in response to an immunogen.
