Our Protein Binding workflow enables protein designers to easily validate protein binders by characterizing their interaction to one or several protein targets of interest. The assay is designed to be flexible in terms of the number of proteins and the number of concentrations to accommodate a wide range of applications. Run in Screening Mode, to quickly test new binders using 2 concentrations, and in Full Affinity Characterization, we perform a more detailed and precise analysis of the binding to a target using 4 or more concentrations.

Protein types

You can test pretty much any type of protein, from small peptides, miniproteins, natural ligands, VHHs, scFvs, or Fabs. We are expressing thousands of proteins every month and see expression success rates of over 90%. For information on how to design your proteins so that they express well, check out our guide here.

Targets

We can work with nearly any soluble protein target that is commercially available, or we can custom express proteins for you. Browse our target catalog for an overview of available targets. If you need a custom or proprietary target, we can help source and prepare the appropriate materials.

//

State-of-the-art biophysical characterization

We use the best label-free sensing methods for protein binding and state-of-the-art instrumentation: Gator Bio for BLI and Carterra for SPR.

//

Proprietary assay optimization and data processing

We've spent the last 2 years building the best binding data-generation pipeline with automated buffer optimization, non-specific binding detection, and custom fitting algorithms. You can trust us to get you the best data possible for your binding experiments.

Project Configurator

Answer a few questions to get accurate pricing and timeline estimates for your project.

Assay Resolution

Do you need precise kinetic constants or just rough estimates?

I only want to know if my designs bind (Yes/No). No need for KDs or kinetic constants.

I want to precisely characterize binding affinity for my designs. I need kinetic constants: KD, Kon, Koff.
