SARS-CoV-2 Spike S1 Protein Antibodies

The SARS-CoV-2 Spike (S) protein is one of the four major structural proteins of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), the causative agent of COVID-19. The SARS-CoV-2 Spike protein has a theoretical molecular weight of approximately 180 kDa and consists of a S1 globular head region which contains the N-terminal receptor-binding domain (RBD) and the S2 stem region that contains the C-terminal fusion domain, two heptad regions, a transmembrane domain, and a cytoplasmic tail. The viral Spike protein binds to the cell surface receptor angiotensin converting enzyme 2 (ACE2) resulting in fusion and virus entry into the cell. We have a catalog of SARS-CoV-2 Spike S1 monoclonal antibodies including human monoclonal, mouse monoclonal, rabbit monoclonal, and fluorescently-conjugated 2019-nCoV Spike S1 antibodies. Validated research applications for SARS-CoV-2 Spike S1 antibodies include Block/Neutralize, ELISA, Flow Cytometry, ICC, IHC, Immunofluorescence, and Western Blot. Browse the technical details, images, and related products to help you choose the viral-specific anti-SARS-CoV-2 Spike S1 antibody that is best suited for your research needs. Each SARS-CoV-2 S1 antibody is fully covered by Novus’ Guarantee+.

SARS-CoV-2 Spike S1 Protein Antibody (1035206) [Unconjugated]

(7 Publications)
100 μg
MAB105403
Western blot shows lysates of recombinant SARS-CoV-2 Spike S1 Subunit and recombinant SARS-CoV-2 Spike RBD. PVDF membrane was probed with 2 µg/mL of Mouse Anti-SARS-CoV-2 Spike S1 Monoclonal Antibody (Catalog # MAB105403) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (HAF018). A specific band was detected for Spike S1 at approximately 90 kDa (as indicated). This experiment was conducted under reducing conditions and using Western Blot Buffer Group 1.

MAB105405
In a functional flow cytometry test, Recombinant SARS-Cov-2 Omicron (B.1.1.529 variant) His-tagged protein (11056-CV) binds to HEK293 human embryonic kidney cell line transfected with recombinant human ACE-2 and eGFP. (A) Binding is completely blocked by 50 µg/mL of Mouse Anti-SARS-Cov-2 Spike 1 Monoclonal Antibody (Catalog # MAB105405) but not by (B) Mouse IgG1 Isotype Control (MAB002). Protein binding was detected with Mouse Anti-His APC-conjugated Monoclonal Antibody (IC050A). Staining was performed using our Staining Membrane-Associated Proteins protocol.
