Compared to traditional solution-phase methods, which are often described as "arduous and laborious" and requiring extensive purification steps like recrystallization, SPPS offers a more streamlined approachWhat is solid phase peptide synthesis?. This method involves the stepwise addition of protected amino acids to a growing peptide chain anchored to a solid support. The excess reagents and byproducts are washed away at each step, simplifying the purification process enormously. This robust methodology forms the basis for the solid-phase synthesis and purification of large peptide components, which can then be further elaborated or assembled.
