Merrifield, revolutionized peptide chemistry by anchoring the growing peptide chain to an insoluble solid support, typically a polymer resin. This strategy simplifies the purification process, as excess reagents and byproducts can be easily washed away after each coupling step. The SPPS cycle involves several key stages: deprotection of the N-terminal amino acid, activation and coupling of the next protected amino acid, and repetitive washing steps. This iterative process allows for the stepwise elongation of the peptide chain until the desired sequence is assembled.
