Biotinylated SARS-CoV-2 (COVID-19) S1 protein (D614G), His, Avitag™ | S1N-C82E3-25ug| Gentaur Distribution US, UK & Europe

It's been reported that coronavirus can infect the human respiratory epithelial cells through interaction with the human ACE2 receptor. The spike protein is a large type I transmembrane protein containing two subunits, S1 and S2. S1 mainly contains a receptor binding domain (RBD), which is responsible for recognizing the cell surface receptor. S2 contains basic elements needed for the membrane fusion.The S protein plays key parts in the induction of neutralizing-antibody and T-cell responses, as well as protective immunity.

Source: Biotinylated SARS-CoV-2 S1 protein (D614G), His, Avitag (S1N-C82E3) is expressed from human 293 cells (HEK293). It contains AA Val 16 - Arg 685 (Accession # QHD43416.1 (D614G) ).
