    The Binding Activity of SARS-CoV-2 Spike RBD Nanobody with SARS-CoV-2-S1-RBD

    Activity: Measured by its binding ability in a functional ELISA. Immobilized SARS-CoV-2-S1-RBD (CSB-YP3324GMY1) at 2 μg/ml can bind SARS-CoV-2 Spike RBD Nanobody, the EC50 is 0.8674 ng/ml.



    In the Colloidal Gold Immunochromatography Assay

    detection system, the background of antibody (CSB-RA33245A2GMY) is clean, the detection limit can be as low as 25ng/ml (1.75ng/0.07ml), and the sensitivity is very good.



    Binding signal of SARS-CoV-2-S1-RBD (CSB-YP3324GMY1) and ACE2 protein-HRP conjugate (CSB-MP866317HU) was inhibited by SARS-CoV-2 Spike RBD Nanobody (CSB-RA33245A2GMY) with the ICC50 is 1.296 nM.



    Binding signal of SARS-CoV-2-S1-RBD (CSB-YP3324GMY1) and ACE2 protein-HRP conjugate (CSB-MP866317HU) was inhibited by SARS-CoV-2 Spike RBD Nanobody (CSB-RA33245A2GMY) with the IC50 is 0.1074 μg/ml.



    SARS-CoV-2 Spike protein RBD His/Sumostar Tag (CSB-YP3324GMY1) captured on COOH chip can bind SARS-CoV-2 Spike RBD Nanobody (CSB-RA33245A2GMY) with an affinity constant of 28.2nM as detected by LSPR Assay.


    ELISA: Immobilize various types of SARS proteins at concentration of 2μg/ml on solid substrate, then react with SARS-CoV-2 Spike RBD Nanobody at concentration of 100μg/ml, 10μg/ml and 1μg/ml。 It shows the SARS-CoV-2 Spike RBD Nanobody (CSB-RA33245A2GMY) is specific for SARS-CoV-2-S1-RBD protein, without any cross-reactivity with MERS-CoV, SARS-CoV, HCoV-OC43 or HCoV-229E。

  • 产品描述:
    This SARS-CoV-2 Spike RBD Nanobody is a recombinant monoclonal antibody generated through the expression of a DNA sequence inserting a human IgG1 Fc domain at the C-terminus, in human embryonic kidney 293 cells (HEK293). The DNA sequence encodes the SARS-CoV-2 spike receptor-binding domain (RBD). The antibody is purified by protein G in vitro. It has been validated with high reactivity towards SARS-CoV-2-S1-RBD by a functional ELISA and good sensitivity for human SARS-CoV-2 spike glycoprotein (S protein) via the Colloidal Gold Immunochromatography Assay (GICA). In neutralization assay, the binding signal of SARS-CoV-2 Spike RBD Nanobody was inhibited by ACE2 protein-HRP conjugated inhibitor, with a 0.1074 μg/ml IC50. Specifically binding and recognizing the RBD of the SARS-CoV-2 spike glycoprotein (S protein), so the SARS-CoV-2 Spike RBD Nanobody can react with samples infected with human coronavirus SARS-CoV-2. But it does not respond to MERS or SARS-CoV spike protein. Akin to other nanobodies, this recombinant nanobody is small and stable, which allows for its reaching to hidden epitopes such as crevices of target proteins.
