We can routinely synthesize peptides exceeding ‌100 amino acids‌ in length, and our longest successfully synthesized linear peptide via advanced solid-phase synthesis technology reaches 156 amino acids‌.

For peptides longer than 100 amino acids, which are widely recognized as extremely challenging to produce, we conduct full case-by-case feasibility assessment, and rely on professional peptide fragmentation and native chemical ligation technology to maximize your ultra-long peptide synthesis success rate.
