Peptide design and synthesis
Neorabio's peptide design and synthesis service combines computational methods with advanced synthetic technologies to help clients design and synthesize peptides with specific functions and properties. Based on target proteins, antigen epitopes, or drug design requirements, we leverage bioinformatics tools to optimize amino acid sequences, ensuring high affinity, stability, and biological activity. The synthesis process employs solid-phase peptide synthesis (SPPS) or liquid-phase peptide synthesis (LPPS), with options for peptide modifications, covalent linkage, and labeling. This service is widely applied in vaccine development, protein–protein interaction studies, antibody discovery, and biopharmaceutical development.
Workflow
Customer provides peptide sequence and modification requirements → Sequence review and synthesis feasibility assessment → Synthesis plan design and quotation confirmation → Peptide synthesis and purification → Quality testing and analysis → Packaging and delivery → After-sales technical support and customized optimization recommendations
