About Us

Qianzhusong Bio, founded in 2021, specializes in peptide reagent services integrating R&D and production. Our strict management system and scientific production processes allow us to synthesize thousands of peptides with different sequences simultaneously, significantly reducing the overall cost and providing cost-effective products and services to researchers, thus saving valuable research time and costs for our customers.

We ensure product quality by meticulously controlling every step from raw material procurement to final product testing. Each peptide synthesis process involves precise data analysis of the chemical and physical properties of the peptide sequences, with detailed records of purification methods, QC reports, mass spectrometry reports, and storage methods.

So far, Qianzhusong Bio has delivered tens of thousands of active peptides to thousands of researchers worldwide, developing synthesis technologies for complex modifications such as methylation, multiphosphorylation, head-to-tail cyclization, various fluorescent labels, and stapled peptides. With our extensive experience and R&D capabilities, we have successfully synthesized sequences exceeding 120 amino acid residues, catering to the diverse needs of our clients.
