Peptide Synthesis Service

Using Automatic peptide synthesizer (PeptrEX), we are capable providing the sequence of amino-acids that customer desire and serve various modification, purity and quantity according to the researchers requests.

Peptide synthesis service of Peptron is certified by thorough quality control system ISO9001.

Synthetic peptides are served as freeze-drying powder form with attachment data from mass analysis and HPLC analysis.

Peptron supplies peptides for more than 500 organization including universities, hospitals and national research institutes. We export products to more than 30 countries all over the world.

All information provided by our customers is considered as confidential and controlled under the strict security settings.

Additional Services

Protein conjugation for antibody production (KLH, BSA, OVA)

It enables manufacture the antibody by artificially increasing the size of peptide antigen which hardly can recognize by antigen presenting cell because of its tiny size and it can induce antibody generation by increasing immune response through T-cell epitope in carried protein

Affinity production service for antibody purification
