Understanding the Foundation: SPPS
When we discuss solid phase peptide synthesis (SPPS), we are looking at the gold standard for creating custom sequences. The process, pioneered back in 1963, involves anchoring the growing peptide chain to an insoluble polymer or resin. This solid phase approach allows for the sequential addition of amino acids, ensuring that each step is clean and efficient.
For those of us interested in the total synthesis of complex molecules like epidermin, the solid phase peptide synthesis method provides the backbone necessary to manage difficult sequences. The peptide chain is constructed step by step, and the ability to wash away excess reagents makes it a superior option compared to liquid phase peptide synthesis for most laboratory environments.
