Target Details

Target: SARS-CoV-2 Spike S1

Target Type: Viral Protein

Background: A new variant of SARS-CoV-2 is spreading in the UK and is rapidly becoming a global threat.It is characterised by multiple mutations in the spike protein. Among them, N501Y is of major concern because it involves one of the six key amino acid residues determining a tight interaction of the SARS-CoV-2 receptor-binding domain (RBD) with its cellular receptor angiotensin-converting enzyme 2 (ACE2).

Molecular Weight: 76 kDa. Due to glycosylation, the protein migrates to 115-140 kDa based on Tris-Bis PAGE result.
