SARS-CoV-2 Antibodies

Detection and inhibition of target proteins

Sequence and structure of the coronavirus SARS-CoV-2 are well understood and appropriate targets for vaccines and therapeutics have been defined. Specific recombinant antibodies against these target proteins are an important tool for further research into the mode of action of the virus and the diverse clinical picture of COVID-19 as well as for drug and diagnostica development. With the help of our partners, we are able to offer you a wide range of specific antibodies and antibody fragments against various relevant SARS-CoV-2 antigens.

The nucleocapsid protein (N) is the most detectable protein in corona viruses. It is very immunogenic and highly conserved. The spike protein (S) on the surface of the virus envelope is essential for virus entry and an important target for antibodies and vaccines. (Walls et al., Cell 2020)

A key enzyme is nsp12 polymerase, with two cofactors essential for nucleotide polymerization, nsp7 and nsp8. (Kirchdoerfer et al., Nature 2020)

CR3022 Variants from Absolute Antibody


The anti-SARS clone CR3022 was first described in 2006. In early 2020,  Tian et al. showed that the clone has a high affinity for SARS-CoV-2 (2019-nCoV). Scientists around the world are investigating this antibody as a candidate for the development of mono- and combination therapies.

Absolute Antibodies offers several engineered formats of the CR3022 clone that open up new experimental possibilities for in vitro and in vivo use, including IgG1, IgG2, IgG3, IgA, IgM, as well as human and murine Fab and Fab2 formats with His tags. Further variants are in work.
