Process Capability : Peptide Design and Sequence Optimization
We provide peptide sequence design, structural optimization, and feasibility assessment based on customer targets. Our team supports modifications such as phosphorylation, methylation, acetylation, biotinylation, fluorescent labeling, and cyclization.
Solid-Phase Peptide Synthesis (SPPS)
We apply advanced solid-phase peptide synthesis technology using Fmoc and Boc chemistry. This enables the synthesis of peptides with varying chain lengths, from short peptides to long-chain and complex sequences, with high efficiency and reproducibility.
Liquid-Phase Peptide Synthesis (LPPS)
For large-scale and cost-sensitive production, we also employ liquid-phase synthesis techniques, suitable for industrial-scale manufacturing of certain peptide products
After-sale Service : Technical Support
We provide professional technical consultation and guidance on product usage, storage, dissolution, and handling. Our technical team is available to assist customers in solving application-related problems and optimizing experimental or production processes.
Quality Assurance and Claims
All products are delivered with a Certificate of Analysis (COA). If any quality issue is identified, customers may contact us within the specified period. We will investigate promptly and offer solutions such as replacement, re-synthesis, or refund based on the actual situation.
Product Customization Service
We offer customized peptide synthesis services according to customer requirements, including sequence design, modification, labeling, and different purity levels. Our team pro
