Process Knowledge¶
Detailed technical documentation for each step of solid-phase peptide synthesis.
Process Steps¶
- SPPS Complete Process — Full SPPS cycle from resin loading to final product
- Resin Loading — Attaching first amino acid to solid support
- Coupling Reaction — Amino acid activation and coupling chemistry
- Deprotection — Fmoc removal and washing cycles
- Cleavage — Peptide release from resin with global deprotection
- Purification — Preparative HPLC purification strategies
- Lyophilization — Freeze-drying to stable peptide powder
- Peptide Folding — Disulfide bond formation for complex peptides
- Custom Synthesis — Modified peptides, labels, and special requirements
- Difficult Sequences — Strategies for challenging peptide syntheses
- Scale-Up Considerations — From laboratory to production scale
Process Relevance by Peptide Type¶
| Peptide Type | Key Process Considerations |
|---|---|
| Linear peptides (<30 AA) | Standard SPPS, straightforward |
| Long peptides (30–50 AA) | Aggregation risk, double coupling |
| Cyclic peptides | Side-chain cyclization after cleavage |
| Disulfide-containing | Oxidative folding, controlled conditions |
| Modified peptides | Special amino acids, post-synthesis modification |
