Biophysical screening

CLS-logo.png

Concept Life Sciences' biology department is renowned for its biophysical assay development, screening, and data interpretation. Extensive biophysical assay expertise allows us to employ the most appropriate biophysical techniques for any given target.

We offer a wide range of assays that provide important information on target engagement throughout the drug discovery process.

We use our biophysical capabilities from hit finding to lead optimization, including extensive use in our fragment-based lead discovery programs. Our biophysical techniques can also provide a full mechanistic, structural, kinetic, and thermodynamic profile of compounds at all stages of the project.

Biophysical screening, assay development and characterisation

Our teams use an array of biophysical techniques for screening purposes, and to increase the understanding of compound-target interactions. These techniques can be used as primary screens, e.g. GCI, SPR or DSF in fragment screening, or as orthogonal, confirmatory assays in biochemical and cellular screening cascades.

Techniques range from simple thermal shift assays to more advanced techniques, such as grating-coupled interferometry (GCI) using a Creoptix® WAVEsystemisothermal titration calorimetry (ITC) using MicroCal® PEAQ-ITC and surface plasmon resonance (SPR) using Biacore® 8k and T200 instruments.

In combination, these techniques can provide vital affinity, stoichiometric, kinetic and thermodynamic data on ligands binding to their target.

All of the biophysical techniques mentioned are equally applicable to small molecules, peptides and biologics, including antibodies.

Our capabilities

  • GCI (Grating-Coupled Interferometry) using Creoptix® WAVEsystem
    Used for: Library screening (including fragment libraries), orthogonal hit verification, hit validation, SAR, affinity profiling (Kd) and kinetic profiling (kon, koff, residence time). Particularly useful for crude samples.

  • DSF (Differential Scanning Fluorimetry) using RT-PCR instruments
    Used for: Library screening (including fragment libraries), orthogonal hit verification, hit validation, SAR and affinity profiling (Kd)

  • SPR (Surface Plasmon Resonance) using either a Biacore T200 or a Biacore 8k
    Used for: Library screening (including fragment libraries), orthogonal hit verification, hit validation, SAR, affinity profiling (Kd) and kinetic profiling (kon, koff, residence time)

  • ITC (Isothermal Titration Calorimetry) using a MicroCal PEAQ-ITC
    Used for: Protein QC, validation of other biophysical techniques, orthogonal hit verification, hit validation, SAR, affinity profiling (Kd) and thermodynamic profiling (ΔG, ΔH, ΔS)
