- Viral Protein
- Background
- The SARS-CoV-2 spike (S) protein variant D614G supplanted the ancestral virus worldwide, reaching near fixation in a matter of months. Recently, that D614G was been found more infectious than the ancestral form on human lung cells, colon cells, and on cells rendered permissive by ectopic expression of human ACE2 or of ACE2 orthologs from various mammals, including Chinese rufous horseshoe bat and Malayan pangolin.
- Molecular Weight
- 136.7 kDa. Due to glycosylation, the protein migrates to 175-230 kDa based on Tris-Bis PAGE result.
