Custom Peptide Synthesis

Custom peptide synthesis is the commercial production of peptides for use in biochemistry, biology, biotechnology, pharmacology and molecular medicine. Custom peptide synthesis provides synthetic peptides as valuable tools to biomedical laboratories. Synthetic oligopeptides are used extensively in research for structure-function analysis (for example to study protein-protein interfaces), for the development of binding assays, the study of receptor agonist/antagonists or as immunogens for the production of specific antibodies. Generally, peptides are synthesized by coupling the carboxyl group or C-terminus of one amino acid to the amino group or N-terminus of another using automated solid phase peptide synthesis chemistries. However, liquid phase synthesis may also be used for specific needs.


Otto Chemie Pvt Ltd highly experienced team of scientists have synthesized oligomers ranging from µg up to multigram quantities. Since our establishment, we have synthesized more than 1,500 different kinds of peptides. The peptides range from di-peptides to peptides having more than 60 Amino Acid residues.

We provide custom peptides synthesis to customers from the biomedical research community, biotechnology and pharmaceutical industry. We have consistently maintained the highest standards of quality, service and technical expertise.
