描述

一般說明

Spike glycoprotein (UniProt: P0DTC2; also known as S glycoprotein, E2, Peplomer protein) is encoded by the S (also known as 2) gene (Gene ID: 43740568) in Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). 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 domain (aa 686-1213), which is reported to be well conserved, is responsible for membrane fusion. This polyclonal antibody binds and neutralizes the SARS-CoV-2 variants including the B.1.1.7; B.1.429; P.1; and B.1.351 at different levels. (Ref.: Ravichandran, S., et al. (2020). Sci Transl Med. 12(550):eabc3539).

應用

Quality Control Testing

Evaluated by Western Blotting with recombinant S1 domain and the extracellular domain of SARS-CoV-2 spike protein.

Western Blotting Analysis (WB): A 1:1,000 dilution of this antibody detected recombinant S1 domain and the complete extracellular domain of SARS-CoV-2 spike protein.

Tested Applications

Enzyme Immunoassay Analysis: A representative lot detected SARS-CoV-2 spike protein S1 domain in ELISA applications (Ravichandran, S., et. al. (2020). Sci Transl Med. 12(550):eabc3539).

Neutralizing: A representative lot neutralized SARS-CoV-2 spike protein S1 domain in Neutralizing applications (Ravichandran, S., et. al. (2020). Sci Transl Med. 12(550):eabc3539).

Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user
