The Role of Solid-Phase Peptide Synthesis in Epilancin 15X Analogue Development

Solid-phase peptide synthesis (SPPS) has revolutionized the way peptides are created in the laboratory.In Vitro Mutasynthesis of Lantibiotic Analogues Containing ... This method involves anchoring the C-terminal amino acid of the desired peptide to an insoluble polymer support (the solid phase). Subsequent amino acids are then added sequentially in a stepwise manner, with each coupling step followed by a deprotection step. This process is highly amenable to automation and allows for efficient purification, as excess reagents and byproducts can be washed away from the solid support.
