Cyclic Peptide

Cyclization is now a common strategy for improving pharmacological properties of a peptide from its linear precursor, including affinity and specificity, proteolytic stability, and/or solubility.

Our team has rich experience in cyclic peptide synthesis, with 80,000+ cyclic peptides successfully delivered.

Modified Peptide

We offer a comprehensive range of special modifications to meet your needs. A few examples are shown below, including N-terminal modification, C-terminal modification, dye/fluorescent labeling, biotin-labeling, PEGylation, post-translational modification, DOTA/NOTA labeling, and isotope labeling.

Automatic and High Throughput Peptide Synthesizer

For routine peptide synthesis, we apply automatic synthesizers to accelerate SPPS portion.   With advanced synthesizers, as well as a variety of prep-HPLC equipment installed in house, your requested compound can be ready within as fast as 5 days.
