Cell-free selection of site-specific polypeptide binders via tethering
In vitro selection method for the engineering of protein-based high-affinity binders to targets of interest with potential pharmacological value
Technology No. 20170034
IP Status: US Patent Issued #10,724,076
The research is at a conceptual stage with some supporting in vitro data. Proof of concept demonstrating the technique can be used to perform a bulk enrichment of the peptide library against a test protein has been obtained.
Applications
- Protein based biologics
- Drug discovery screening
Technology Overview
A new method for isolating and identifying biomolecules that bind to a specific target epitope. This novel technology combines cell-free display, engineered protein scaffold libraries, and disulfide tethering methods into one optimized protocol that selectively enriches for polypeptides that are target-site specific. This technology can be used to identify polypeptide therapeutics for treating a broad range of diseases including cancer, where it is critical to ensure therapeutics target cancerous mutations without affecting normal proteins.
