Product Description
SARS-CoV-2 S2 Protein (Pre-fusion) Binding Antibody, Mouse Monoclonal [MA151B-100 or MA151B-025]
GenHunter is now offering 13 monoclonal antibodies against SARS-CoV-2 (Hu-1/WT, Beta, Delta, Omicron BA.1, Omicron BA.2, Omicron BA.2.76, Omicron BA.4, Omicron BA.5, Omicron XBB.1.5, Omicron EG.5, Omicron JN.1, and Human ACE2; more details below and in "Ordering" tab), 9 different SARS-CoV-2 antigens (Hu-1/WT, Beta, Delta, Omicron BA.1, Omicron BA.5, Omicron XBB.1.5, Omicron EG.5.1, Omicron JN.1, & Human ACE2), and 2 COVID-19 Neutralizing Antibody Rapid Test Kits (for the Omicron JN.1 or Omicron XBB.1.5 variants).
SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2), also known as COVID-19 coronavirus or 2019-nCoV, can infect human respiratory epithelial cells by interacting with the human ACE2 receptor. The spike protein is a large type I transmembrane protein composed of two subunits, S1 and S2. S1 primarily contains a receptor-binding domain (RBD) responsible for recognizing the cell surface receptor, while S2 includes the essential elements for membrane fusion. The S protein plays a crucial role in inducing antibody and T cell responses, as well as protective immunity. The main functions of the spike protein can be summarized as follows: mediating receptor binding and membrane fusion, defining the host range and viral specificity, serving as the primary target for neutralizing antibodies, being a critical target for vaccine design, and enabling transmission between different hosts through genetic recombination or mutations in the receptor-binding domain (RBD).
