Our Business


Role of Our Division in Sapporo

Cosmo Bio has its Sapporo division in Otaru, Hokkaido, which is responsible for developing and manufacturing life science-related reagents. Based on the primary cell culture technology developed over many years by Primary Cell Co., Ltd., the predecessor of the Sapporo division, we began providing peptide synthesis and antibody production services as a new business in 2016. We are also engaged in protein production utilizing chicken egg bioreactors. Simply relying on the trading company's ability to purchase and sell quality products is not enough to fully meet the needs of researchers. We commercialize our new merchandise based upon the opinions and perspectives of researchers in order to appropriately satisfy demands.

Custom Peptide Synthesis and Antibody Production Services

The peptides are custom synthesized in the sequence that meets the researcher's needs. In addition to supporting reserach at universities and other institutions, we provide products and services that support drug discovery by pharmaceutical companies.
We also offer contract services for the production of antibodies using this peptide as a material (antigen).

Main service items

Custom Peptide Synthesis

Peptide synthesis, AQUA-grade peptide design and synthesis services, etc.

Antibody Production Services

Epitope design service "MODERAGON" polyclonal antibody production, monoclonal antibody production, etc.

Contract production and production of proteins using an egg bioreactor

Protein production using an egg bioreactor is a technology that produces large quantities of specialized proteins in the eggs of chickens with genome editing. It was developed and patented by Dr. Isao Oishi of the National Institute of Advanced Industrial Science and Technology (AIST). We began joint research in 2015 and have been working on the commercialization of this technology with the support of New Energy and Industrial Technology Development Organization (NEDO) and Japan Science and Technology Agency (JST).
As a result of these efforts, the company began manufacturing and commercializing its own proteins. The contract manufacturing business launched in July 2019; large quantities of proteins are purified, produced, and delivered to users in need. We utilize domestic Japanese patented technologies that avoid complex licensing issues in the manufacturing process. We are committed to creating products solely employing Japanese technology.
