SARS Coronavirus 2 (COVID-19) Research Reagents

ProSci Incorporated’s SARS-CoV-2 Spike Antibody (Cat. No. 3525) immediately met researchers’ needs at the outset of the COVID-19 pandemic and as a result is one of the most cited antibodies used in SARS-CoV-2 and COVID-19 research. ProSci now provides antibodies and recombinant proteins representing the entire SARS-CoV-2 proteome as well as for viral cellular entry factors ACE2, TMPRSS2, and Furin.

Since the pandemic outset, however, multiple SARS-CoV-2 variants have appeared which demonstrate greater transmissibility of the virus (Nextstrain). In particular, the spread of Alpha variant (N501Y) as a Virus of Concern (VoC) with Spike protein mutation P681H expanded at such a rapid rate from February 2021 through May 2021 that incidence rose to 50% of worldwide COVID-19 cases. Delta has become a more recent VoC and is quickly displacing the Alpha variant. To better understand the role played by spike protein cleavage in SARS-CoV-2 biology and COVID-19 pathology, ProSci Incorporated is the first to offer an antibody specifically against the SARS-CoV-2 Alpha variant P681H mutation (Cat. No. 9359).
