Recombinant proteins are proteins obtained by recombinant DNA technology. The host cells used to produce recombinant proteins are mainly E.coli cells (prokaryotic expression system) and yeast cells (eukaryotic expression system).

Recombinant proteins have been widely used in therapeutic recombinant protein drugs and drug carriers, preventive recombinant protein vaccines, immunoassay reagents, diagnostic reagent development, etc., and play an important role in most popular research fields such as antibody drug target screening, CAR-T cell therapy, CDC conjugated drugs, enzyme preparations, influenza virus proteins, and cytokines.

In the field of recombinant protein services, Yaohaibio can provide one-stop CMC services for various types of recombinant proteins, including cytokines, carrier proteins, recombinant polypeptides, enzymes, allergens, VLPs, vaccines and other types of recombinant proteins.

Yaohaibio dedicates to developing a stable recombinant protein CDMO service platform, which can provide customers with whole life cycle services such as gene engineering strain construction, strain bank establishment, lab-scale process development/optimization, pilot-scale process scale-up production, IND application and clinical sample preparation, quality specification establishment, analytical method development/validation, quality management system establishment, NDA registration and application and commercial production (MAH) to satisfy customers with commercial requirements for different stages of recombinant protein drug product development. With rich experience in process development and production, we are committed to serve the customers in efficient and high-quality manner.

Yaohaibio has an integrated CMC development and cGMP production process platform to produce recombinant proteins, plasmids, and DNA fragments with E.coli and yeast expression systems.
