SARS-CoV-2 antibodies and proteins

SARS-CoV-2 antibodies and proteins


The newly identified coronavirus, SARS-CoV-2 (previously known as 2019-nCoV) shares 79.5% sequence identify with SARS-CoV. The viral genome encodes spike, envelope, membrane, nucleocapsid, and multiple non-structural proteins. arigo offers quality antibodies and proteins to facilitate the research of SARS-CoV-2.


● Spike protein and ACE2 

SARS-CoV-2 cell entry depends on viral spike protein and ACE2 which mediates conversion of Angiotensin II to Angiotensin 1-7. The receptor-binding domain (RBD) of the spike protein is essential for ACE2 binding. Blocking the interaction of spike protein and ACE2 is a potential therapeutic approach for COVID-19 treatment.
