Solid phase peptide synthesis requires large amounts of organic solvents, which makes the transition toward the synthesis of peptides in aqueous media a vital step for those of us committed to greener laboratory practices.
In my experience, the shift toward aqueous solid support for peptide synthesis—such as the use of specialized PEG-PS resins—has made it possible to synthesize medium-sized peptides of up to 20 amino acids with increasing reliability. This appr Jun 18, 2025 — SPPS is generally considered more efficient for most applications, but LPPS has advantages in specific scenarios. oach effectively addresses the sustainability challenges in peptide synthesis and purification, proving that we do not always need to rely on toxic chemicals to achieve high-quality results.
Practical Insights into the Methodology
When learning how solid phase peptide synthesis is performed, one must appreciate the cycle of coupling and deprotection. Whether you are performing manual Fmoc solid-phase peptide synthesis or utilizing automated systems, the core principles remain the same. The process involves anchoring the C-terminus of the growing chain to an insoluble polymer, allowing for the sequential addition of amino acids.
I often compare this to a controlled assembly line. While solid-phase peptide synthesis (SPPS) is the gold standard for most, I have also explored Liquid-phase peptide synthesis (LPPS) for specific scenarios. However, SPPS is generally considered more efficient for most applications due to the ease of washing away excess reagents between steps.
Key Considerations for Your Setup:
* Resin Selection: The support medium is critical. Using aqueous compatible supports is essential for water-based protocols.
