    Shedding light on Sybody® candidates binding onto SARS-CoV-2 spike RBD

    In this TechNote we show how the WAVE system can be used to understand the binding dynamics of Sybody® candidates to the receptor binding domain (RBD) of SARS-CoV-2, both provided by Linkster Therapeutics AG and the University of Zürich. With high sensitivity and robust microfluidics, the WAVEsystem is suitable for competition assays, confirming and enriching ELISA data. By providing a rapid kinetic characterization for inhibition assays, with ACE2 kindly provided by leadXpro, the WAVE is accelerating the development of therapeutics against SARS-CoV-2.

    Biologics Development

    Real is natural

    The Creoptix® WAVEsystem enables researchers to study biologic drugs in a wide range of biofluids and other complex matrices. With superior sensitivity to traditional Surface Plasmon Resonance (SPR) technologies for more accurate measurement of binding affinity and binding kinetics, the Creoptix WAVEsystem is driving biologics development.

    Sybody® candidates compete for ACE2 binding onto SARS-CoV-2 Spike RBD

    Rapid kinetic characterization for inhibition assays

    Listen to Markus Seeger (University of Zurich) and Rony Nehmé (Creoptix) discuss binding affinities and selectivity of Sybody® candidates to the receptor-binding domain (RBD) region of SARS-CoV-2 Spike protein. Highlights:

    • Why ELISA signals alone are not enough to predict potency in biologics development
    • Why did Markus choose the WAVEsystem for the biomolecular interaction analysis at his lab?
    • Why choosing the right candidates at the very early stages of research matters.

    Augmented affinity in antibody-antigen interactions: impact on design of diagnostic assays

    Presented by Mologic at PEGS Boston 2019

    Anti-p24 antibody binding kinetics were measured using the Creoptix WAVEdelta system. The results of this study reveal a surprising enhancement in affinity due to a significant 21-fold increase in on-rate when anti-p24 mAb1 recognizes the anti-p24 mAb2-p24 complex.
