About Us

MOL Changes

MOL Changes has unique technical capabilities in peptide synthesis, peptide modification, protein and peptide labeling and cell reactions. The company’s technical personnel are all from the fields of organic chemistry and biology. The technical leaders are composed of graduate students and doctors. They have mastered a variety of peptide synthesis methods, including solid-phase peptide synthesis, liquid-phase peptide synthesis, liquid-solid combined peptide synthesis, reverse solid-phase peptide synthesis and microbial fermentation.

We provide a wide range of synthetic R&D services for drug development, biological research and bioengineering, and provide scientists with a feasible way in the process of new drug development. The value of the peptide synthesis provided is far more than just long sequences and high purity. We have mastered unique technologies to solve the synthesis of complex and difficult peptide sequences, which can effectively overcome compatibility issues in the process of peptide synthesis and assist customers in providing comprehensive optimization strategies during the research process.

The R&D, synthesis, purification, freeze-drying and testing links are all completed in sterile purification laboratories. At present, scientific research laboratories and branches have been established in Changsha, Zhuzhou and Hong Kong. Customers mainly come from the United States, Canada, Russia, the United Kingdom, Australia, Sweden, Norway, South Korea and other countries, covering biochemistry colleges, biochemistry institutes, medical research institutions and biological scientists.

In the future, MOL Changes will continue to focus on technology research and development in order to become a leading company in single peptide products, establish strong technical and cost advantages in this field, and help customers dominate the market.
