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

Recombinant proteins have been widely used in the fields of 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 directions such as antibody drug target screening, CAR-T cell therapy, CDC conjugate drugs, enzyme preparations, influenza virus proteins and cytokines.

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