Comprehensive Custom Peptide Synthesis Capabilities
From Sequence Design to Impurity Control — We Deliver More Than Peptides, We Deliver Solutions
Successful peptide development hinges not only on synthesis, but also on a thorough understanding of sequence complexity, structural behavior, modification strategy, and quality risk control.
We provide end-to-end custom peptide solutions, supporting clients from early research through advanced preclinical and pharmaceutical applications.
Section 01
Customized Amino Acid Sequences
Designing Challenging Sequences
Broad Length Coverage
Reliable synthesis of peptides ranging from short sequences (2–10 amino acids) to long peptides exceeding 100 amino acids, with consistent yield and batch reproducibility.
Special and Non-Natural Building Blocks
Full compatibility with D-amino acids, non-natural amino acids (e.g. Cit, Orn, Abu), β-amino acids, and other customized monomers beyond the 20 canonical amino acids.
Advanced Solutions for Difficult Sequences
Targeted strategies for highly hydrophobic, aggregation-prone, or cysteine-rich peptides, supported by sequence feasibility evaluation, optimized coupling protocols, and microwave-assisted peptide synthesis technologies.

Salt Form & Counter-Ion Control
Precision Down to the Final Chemical Form
Salt form selection plays a critical role in peptide stability, solubility, and experimental reproducibility. We provide precise control tailored to downstream applications.
- Common Salt Forms: TFA salts (default), Acetate salts, and Hydrochloride (HCl) salts.
- Desalting: Ultra-low residual TFA levels (<1%) achievable.
- Customized: Sodium, ammonium, and other customized salt forms available.
