Validation Data Gallery

Filter:
  • Western Blot (WB) analysis of various lysates using SARS-CoV-2 S protein (319-541 aa) Polyclonal antib (28991-1-AP)

    WB analysis using 28991-1-AP

    E.coli expressed SARS-CoV-2 spike protein (Cat.NO. Ag30688) was subjected to SDS PAGE followed by western blot with 28991-1-AP (SARS-CoV-2 S protein (319-541 aa) antibody) at dilution of 1:2000 incubated at room temperature for 1.5 hours.

  • ELISA experiment of Recombinant protein using SARS-CoV-2 S protein (319-541 aa) Polyclonal antib (28991-1-AP)

    ELISA experiment of Recombinant protein using 28991-1-AP

    SARS-CoV-2 Spike Glycoprotein Antibody (28991-1-AP) tested by ELISA. SARS-CoV-2 Spike Glycoprotein (319-541 aa) were coated onto microtiter plates at 0.15 µg/well and then incubated with a dilution series of SARS-CoV-2 Spike Glycoprotein Antibody (28991-1-AP). Bound antibodies were detected with HRP conjugated Goat anti-Rabbit IgG followed by incubation with HRP Substrate and teminated with H2SO4, then measuring the resulting absorbance at 450 nm.

Background Information

Coronaviruses (CoVs) infect human and animals and cause varieties of diseases, including respiratory, enteric, renal, and neurological diseases. CoV uses its spike protein to recognize ACE2 as its receptors and mediate membrane fusion and virus entry into host cells(PMID: 32221306). Each monomer of trimeric S protein is about 180 kDa, and contains two subunits, S1 and S2,S1 recognizes and binds to host receptors, and subsequent conformational changes in S2 facilitate fusion between the viral envelope and the host cell membrane(PMID: 19198616). Although the amino acid sequences of the S-glycoprotein were found to be different between the various HCoV, the structures showed high similarity, but the best 3D structural overlap shared by SARS-CoV and SARS-CoV-2, consistent with the shared ACE2 predicted receptor (PMID: 32522207). The spike protein of CoVs can be a target for vaccine and therapeutic development (PMID: 19198616). 28991-1-AP is specific for spike protein of SARS-COV-2, that antigen region is 319-541aa.
