Custom Peptide Synthesis: From Sequence Design to Delivery

How does the custom peptide synthesis process work? From sequence submission to final delivery, here's what researchers need to know.

Custom peptide synthesis allows researchers to obtain peptides with specific sequences, modifications, and purities tailored to their experimental needs. The solid-phase peptide synthesis (SPPS) process is the industry standard.

The Process

1) Sequence submission and feasibility review, 2) Synthesis via Fmoc or Boc SPPS, 3) Cleavage and crude purification, 4) HPLC purification to target purity, 5) Analytical QC (HPLC, MS, amino acid analysis), 6) Lyophilization and packaging, 7) COA generation and cold-chain shipping.
