Monoclonal antibodies (mAbs) have revolutionized the therapeutic landscape over the last two decades, becoming one of the most significant classes of drugs in the global pharmaceutical market. Today, the global mAbs market is valued at hundreds of billions of dollars, driven by their high specificity and efficacy in treating oncology, autoimmune diseases, and infectious pathologies.
Industrial manufacturing of mAbs requires sophisticated bioprocessing technologies. As the demand for biosimilars and innovative antibody-drug conjugates (ADCs) rises, the pressure on the supply chain for high-quality intermediates and raw materials has intensified. This is where China’s top suppliers have stepped in to bridge the gap between high demand and cost-effective production.
Hangzhou Jeci Biochem Technology Co., Ltd. is located in Hangzhou, Zhejiang Province. We are committed to sales of active pharmaceutical ingredients, pharmaceutical intermediates, nutritional products and food additives, cooperative R & D, custom manufacturing, sales and service as well as import of these kinds of materials.
In China, we have a strong collaborative R&D team, working in depth with new drug research institutes and multiple custom processing plants. We have very good domestic sales channels and have long-term relationships with domestic companies, including product applications, technology transfer, product supply, custom processing, and exclusive agents for multiple products in multiple regions. In addition, we also provide factory quality management system certification consulting services.
