4. Technical Advantages and Disadvantages of Synthesis Methods

Peptides made from solid-phase synthesis (SPPS) offer significant advantages in yield consistency and scalability. SPPS achieves coupling efficiencies of 99.5% per step, resulting in overall yields of 85-95% for sequences up to 40 residues. In contrast, peptides made from liquid-phase synthesis (LPPS) typically achieve 70-85% yield for similar lengths, though LPPS may be preferred for large-scale production (>100g) due to lower solvent consumption. However, purification costs for peptides made from SPPS increase by approximately 15% per additional amino acid residue, making LPPS more cost-effective for long sequences (>50 residues). The trade-off is clear: peptides made from SPPS provide superior purity and reproducibility for research applications, while peptides made from LPPS may be suitable for bulk industrial uses where absolute purity is less critical.
