ZooMAb antibodies represent an entirely new generation of recombinant monoclonal antibodies.
Each ZooMAb antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb antibodies are reliably available and ready to ship when you need them.

特異性
Clone hu2B3E5 is a chimeric ZooMAb monoclonal antibody that specifically detects SARS-CoV-1/2 Spike protein. It targets an epitope within the extracellular domain.
ZHU1076 combines variable regions of mouse monoclonal antibody anti-SARS-CoV-1/2 Spike protein (ZMS1076) and constant region of human IgG1. We recommend an anti-human antibody as secondary antibody for detection (Example: AP309P Goat anti-human IgG antibody HRP).

標靶描述
SARS-CoV-1/2 Spike glycoprotein (UniProt: P59594/P0DTC2; also known as S glycoprotein, E2, Peplomer protein) is encoded by the S gene (Gene ID: 1489668/43740568) in SARS-CoV-1/2 virus. The SARS-CoV-2 is a positive-strand RNA virus that causes severe respiratory syndrome in human. The mature SARS-CoV-2 contains 4 structural proteins: Envelope (E), Membrane (M), Nucleocapsid (N), and the Spike protein (S). E and M proteins help in viral assembly and N protein is needed for RNA synthesis. The S protein is a single-pass type I, homotrimeric, membrane glycoprotein that is responsible for virus binding and entry into host cell. It is synthesized with a signal peptide (aa 1-12), which is subsequently cleaved off to generate the mature protein that contains an extracellular domain (aa 13-1213), a transmembrane domain (aa 1214-1234), and a cytoplasmic domain 1235-1273). The S protein is further processed into S1 (aa 13-685) and S2 (aa 686-1273) subunits by host cell furin. The presence of a furin polybasic cleavage site in S protein from SARS-CoV-2 sets it apart from S protein in SARS-CoV that possesses a monobasic S1/S2 cleavage site. The S1 subunit has the receptor binding domain (RBD; aa 319-541) that mediates entry of SARS-CoV-2 into sensitive cells through the peptidase domain of host Angiotensin-converting enzyme 2 (ACE2) with high affinity (KD = 15 nM). The S2 protein, which is reported to be well conserved, is responsible for membrane fusion. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals. This chimeric version was generated using FC region of human IgG.
