Biovision | Human CellExp™ SARS-CoV-2 Spike RBD (L452R, T478K), Recombinant | P1744

Description: SARS-CoV-2 Spike protein is a large type I transmembrane protein composed of S1 subunit and S2 subunit. During viral infection, the receptor-binding domain (RBD) of the S1 subunit is responsible for the recognition and binding of host receptor ACE2, while the S2 subunit mediates viral cell membrane fusion. The SARS-CoV-2-S1-RBD/ACE2 interaction mediates viral entry into the target cells. The mutations at L452R and T478K were identified in the SARS-CoV-2 Delta (particularly B.1.617.2) variants that originated in India.
