Liquid-phasepeptide synthesisprotocol The field of peptide synthesis has undergone significant advancements, moving beyond traditional methodologies to embrace more efficient and sustainable approaches. Among these innovations, tag-assisted peptide synthesis (TAPS) has emerged as a powerful technique, offering a compelling alternative to established methods like Solid Phase Peptide Synthesis (SPPS). This article delves into the intricacies of tag-assisted peptide synthesis, exploring its principles, advantages, and its growing impact on the development of peptide-based therapeutics.

Understanding the Core of Tag-Assisted Peptide Synthesis

At its heart, tag-assisted peptide synthesis involves the strategic use of a tag moleculeSolid Phase Peptide Synthesis (SPPS), invented by Merrifield in 1963,[1]is the current state of the art for manufacturing of peptide therapeutics.. This tag, often a soluble anchor molecule or pseudo-solid phase protection, is attached to the growing peptide chain. This attachment serves a crucial function: it keeps the peptide soluble in the reaction system, facilitating purification and handling during liquid-phase peptide synthesis (LPPS). Unlike traditional solid-phase methods where the peptide is anchored to an insoluble resin, tag-assisted liquid-phase peptide synthesis (LPPS) allows the entire synthesis to occur in solution, with the tag acting as a temporary solubilizing and anchoring agent.作者：H Li·2024·被引用次数：3—TAG-assisted peptide synthesis technologyenables optimal conservation of Fmoc amino acid raw materials and chemical solvents while ...
