SAXS-enabled Studies of mAbs Improve Detection of SARS-CoV-2 Nucleocapsid Protein & Reveal Conformational Plasticity-dependent Potency Changes

About the Webinar

Small angle X-ray Scattering (SAXS) enables biological systems to be imaged in an aqueous solution, closer to their natural state. It allowed the researchers to visualize the flexibility of antibodies in solution and show how conformational variability of the antigen-binding regions affects antibody pairing. Unexpectedly, the biophysical flexibility of these antibodies correlates with and can modulate their potency. We recently showed how monoclonal antibodies' rigidity leads to increased sensitivity in the detection of nucleocapsid protein from SARS-CoV-2. We employed SAXS and molecular modeling and show how mAb conformational variability affects antibody pairing with SARS-CoV-2 nucleocapsid protein. We propose that the pairing of rigid antibodies can expedite the development of sensitive and selective antigen-detecting point-of-care lateral flow assay devices, which are key for the early diagnosis of SARS-CoV-2 and other pathogens.

Keynote Speakers

  • Michael Piazza, Ph.D.

    Michal Hammel, Ph.D.
    • Research Scientist at Lawrence Berkeley National Laboratory
    • Founder of SAXS Consulting, Inc

    As a scientist at the Lawrence Berkeley National Laboratory (LBNL), I integrate biological small angle X-ray scattering (SAXS) and X-ray crystallography. To make the technique accessible to more investigators and push SAXS onto a new paradigm, we have been the first to create a high throughput SAXS capability. I predicted an increase in impact from SAXS, which has mostly come true.

  • Soleil Grisé

    Curtis D. Hodge, Ph.D.
    • Postdoctoral Fellow at Lawrence Berkeley National Laboratory
    • Co-Founder & CEO of Nanotein Technologies, Inc.

    By leveraging my experience in cellular biology and cancer immunology, with my expertise in structural biology and biochemistry, I use a cross-disciplinary approach to solve biological problems and innovate new technologies.
