Protein Scaffold for Molecular Targeting Ligands (20140059, Dr. Benjamin Hackel)
Non-immunoglobulin Based Protein Scaffolds
The next generation of non-immunoglobulin based (i.e. non-antibody) protein scaffolds for use in immunotherapies and medical diagnostics has been developed. The protein scaffolds are smaller and more stable than comparable antibody scaffolds, which improves their physiological distribution. Additionally, these scaffolds bind with high affinity to their targets and can be easily customized for specific molecular targets. These characteristics strongly improve retention at the target site.
Antibody-antigen bond specificity is a crucial aspect of effective immunotherapies and medical imaging. These protein scaffolds offer improved performance compared to current antibody techniques.
Protein Scaffold Applications
This technology has a wide range of applications. The protein scaffolds are effective for molecular targeting to neutralize a target protein, drug delivery to specific cells, such as tumor cells, and tumor imaging through attachment of a fluorophore to the protein scaffold. The scaffolds have low toxicity and have a cost-efficient production process through chemical synthesis or recombinant, bacterial methods.
