The Foundation: Understanding Solid Phase Peptide Synthesis (SPPS)
At its core, Solid Phase Peptide Synthesis (SPPS) is a stepwise method for assembling peptides on a solid support. This revolutionary technique, which transformed the landscape of chemical biology, allows researchers to anchor a growing chain to an insoluble polymer resin. By utilizing Fmoc/tBu strategy—where the N-terminus is protected by a fluorenylmethyloxycarbonyl group—we can ensure high-fidelity coupling of amino acids.
