In addition to recombinant subunit vaccines targeting pathogen antigens, researchers have focused on targeting proteins in tumor cells or other metabolic pathway-related antigens. These antigens can stimulate the body to produce specific antibodies that kill tumor cells or block target metabolic pathways, achieving the goal of treating diseases.
Based on a comprehensive "recombinant protein service platform," Yaohai Bio-Pharma can provide customers with a one-stop solution from strain development and protein sample preparation to GMP production of recombinant protein vaccines. We can flexibly adjust the service process according to the customized needs, providing customers with high-quality recombinant protein Drug Substance (DS) or Drug Product (DP) in multigram or tens of grams, as well as process development and GMP production records, and testing reports.
One-stop Solution for Protein/Peptide Therapeutic Vaccines
The recombinant protein/peptide therapeutic vaccine services offered by Yaohai Bio-Pharma are also based on the [recombinant protein service platform]. For more details about the service, please refer to the "Recombinant Subunit Vaccine CDMO Services".
