  • Background
    The newly identified 2019 novel coronavirus (SARS-CoV-2) has posed a serious threat to human health, and it spreads quickly. It is helpful to develop the Anti SARS-CoV-2 neutralizing antibody titer serologic assay kit to test the protective neutralizing antibody level in serum.
  • Application
    The kit is developed for qualitative detection or titer measurement of Anti-SARS-CoV-2 (BA.2.12.1) neutralizing antibody (Spike RBD) in human serum.

    It is for research use only.

  • Reconstitution
    Please see Certificate of Analysis for details of reconstitution instruction and specific concentration.
  • Storage & Shipping
    The unopened kit is stable for 12 months from the date of manufacture if stored at 2°C to 8°C.

    The opened kit should be stored per components table. The shelf life is 30 days from the date of opening.

    The kit shipped at room temperature that had been validated. Please contact us if you need blue ice shipping, but additional freight may be followed.

  • Assay Principles
    This assay kit is used to measure the levels of Anti-SARS-CoV-2 neutralizing antibody through a competitive ELISA. The microplate in the kit has been pre-coated with Human ACE2 protein. First serum samples, Positive control, Negative Control are added to the wells followed by addition of HRP-SARS-CoV-2 Spike RBD. After incubation, the wells are washed and substrate is added to the wells. The reaction is terminated by the addition of stop solution and the intensity of color is measured at 450 nm. The presence of neutralizing antibodies in samples will compete with ACE2 for HRP-SARS-CoV-2 Spike RBD binding. The intensity of assay signal decrease proportionally to the presence of Anti-SARS-CoV-2 neutralizing antibody.

    Your experiment will include 5 simple steps:

    a) All reagents were returned to room temperature(20°C-25°C) before use.

    b) Make series the tested sample and control with ditlution buffer, HRP-SARS-CoV-2 RBD diluted with dilution buffer.

    c) Add the HRP-SARS-CoV-2 RBD, diluted sample and Control add the plate respectively.

    d) Wash the plate and add TMB or other colorimetric HRP substrate. e) Stop the substrate reaction by add diluted acid. Absorbance (OD) is calculate as the absorbance at 450 nm minus the absorbance at 630 nm to remove background prior to statistical analysis. The OD Value reflects the amount of protein bound.
