Functional Peptides from One-bead One-compound High-throughput Screening Technique

C ombinatorial chemistry provides a cost-effective method for the rapid discovery of new functional peptides. One-bead one-compound(OBOC) high-throughput screening technique offers a lot of structurally diverse peptides to be rapidly synthesized and screened for binding to a target of interest. The OBOC peptide library screening involves three main steps: library construction, positive beads separation, and peptide sequencing. This review mainly summarizes some special technique tips during functional peptide screening and potential future directions of the OBOC high-throughput screening technique.
