Sars Spike Protein Antibody Summary

The antibody was developed by immunizing rabbits with a synthetic peptide corresponding to amino acids 1124-1140 (C-QPELDSFKEELDKYFKN) from the S (Spike glycoprotein)(Spike protein S2') for the Human SARS coronavirus (Genbank accession no. NP_828851.1)
Full length Spike protein transfected into UM92 cells was used as a positive control and an approximate 139 kDa band was observed. Dot Blot results using recombinant proteins for cross-reactivity testing revealed high reactivity to SARS-CoV-2 Spike Protein, 1000-1200 a.a. (NBP2-90973) and low/no reactivity towards MERS Spike 2 or H1N1 (NBP1-99041).

It has recently been shown that SARS (severe acute respiratory syndrome) is caused by a human coronavirus. Human coronaviruses are the major cause of upper respiratory tract illness, such as the common cold, in humans. Coronaviruses are positive-stranded RNA viruses, featuring the largest viral RNA genomes known to date (27-31 kb). The first step in coronavirus infection is binding of the viral spike protein, a 139-kDa protein, to certain receptors on host cells. The spike protein is the main surface antigen of the coronavirus. The glycosilated spike protein (as well as the nucleocapsid protein) can be detected in infected cell culture supernatants with antisera from SARS patients.

FAQs for Sars Spike Protein Antibody (NB100-56578). (Showing 1 - 3 of 3 FAQs).

  1. Do you know if Sars Spike Protein Antibody (16F1071) will cross react with SARS-2?
    • NBP2-24746 has no similarity unfortunately. However, NBP2-24808, NBP2-24942, and NB100-56578 have 100% sequence homology with the SARS-CoV-2 Spike Protein.
  2. I am looking for a primary antibody to sars spike protein to the new COVID-19.
    • NBP1-28850, NB100-56578, NBP2-24808, NBP2-24942 have 100% homology to the new SARS-CoV-2 virus.
  3. Hello can you help me to identify detection antibody for COvid-19 spike protein? NB100-56578 is for spike of the Covid-19 not for the original SARS virus correct?
    • NB100-56578 was originally developed to the original SARS virus, but the homology of the target sequence of this antibody to the spike protein for COVID-19 is identical, so we can guarantee that it will work for COVID-19 detection.
