| 产品简介(Background) | SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2) also known as 2019-nCoV (2019 Novel Coronavirus) is a virus that causes illnesses ranging from the common cold to severe diseases. Spike Protein, the main surface antigen of the coronavirus, is a ∼180kD glycoprotein that crucial for viral fusion and entry into the host cells. It is a homotrimeric, consisting of two subunits, S1 and S2. In SARS-CoV-2, proteolytic cleavage of spike protein into S1 and S2 subunits is required for its activation. The first step of coronavirus infection of virus is the interaction of the spike protein to certain receptors on host cells. The S1 subunit is focused on attachment of the protein to the receptor while the S2 subunit is involved with membrane fusion. The receptor binding domain (RBD) locates in the C-terminal region of S1, and it binds to Angiotensin-Convertin434g Enzyme 2 (ACE2) of host cells with high affinity and fast binding kinetic. Blocking the interaction between ACE2 and RBD inhibits the viral infection. RBD-specific antibodies have been shown to inhibit the attachment of RBD to ACE2-expressing cells, suggesting RBD as a potential target for vaccinations or therapy of SARS-CoV-2 infection. The attributes of Delta variants: Increased transmissibility; Potential reduction in neutralization by some EUA monoclonal antibody treatments; Potential reduction in neutralization by post-vaccination sera. |
