R&D Systems Proteins for Coronavirus Research

R&D Systems, a Bio-Techne brand, offers a wide selection of bioactive recombinant proteins for COVID-19 research, including the U.K., South African, and Brazilian variant Spike proteins. As the COVID-19 pandemic evolves and new mutant variants are identified, we are striving to provide researchers with the tools they need in the fight against coronavirus. We now offer over 100 different Spike proteins including the receptor binding domain (RBD), S1, S2, and full ectodomain Spike proteins from SARS-CoV-2 to SARS and MERS coronaviruses and more. For human ACE-2, His-tagged, Fc chimera, and Avi-tag options are available as well has ACE-2 from 8 other species. Every protein we manufacture for coronavirus research is produced and purified in-house and is rigorously tested for bioactivity and lot-to-lot consistency.

New SARS-CoV-2 Variants

The emergence of the U.K. (B.1.1.7), South African (B.1.351), and Brazilian (P.1) variants across the globe has heightened our level of concern about SARS-CoV-2’s ability to evolve into a more infectious and deadly virus. As the SARS-CoV-2 virus mutates and new variants of concern are identified, we are quickly developing the latest mutant proteins to enable scientists to advance their research and stay ahead in this ever-changing COVID-19 landscape.
