Biological assays for the development of therapeutics
Regardless of the disease model, identifying a target for treatment is imperative for the development of therapeutics. In certain cases, this target may be on a micro-scale – spanning only a few amino acids on a protein or cell surface. Peptide libraries are ideal for discovering novel therapeutic strategies because they display hundreds of peptide combinations in parallel, grossly decreasing the time and effort required to identify target sequences.
In this regard, peptide libraries can serve as biological assays: by adding cells or microbes to an array of peptides, researchers can easily trace a variety of biological outcomes from cell differentiation to cytotoxicity.
