Low-cost synthesis of peptide libraries and their use for binding studies via temperature-related intensity change

Abstract

Summary: Protein-peptide interactions are involved in many fundamental cellular functions and constitute promising drug targets. Here, we provide a detailed protocol for the cost-effective preparation of a cellulose-based solid support for synthesis of nanoscale to micromolar-scale peptide libraries. Their subsequent use for high-throughput protein interaction screening as well as affinity determination in solution provides binding data for thousands of unique peptides with a turnover of 1 to 2 weeks, thereby facilitating in vitro assessment and development of high-affinity binders.For complete details on the use and execution of this protocol, please refer to Schulte et al., (2020)
