About Us

Recombinant Protein

Growth Factor, Insulin, etc

Recombinant protein therapies – including major biologics like monoclonal antibodies – are produced by inserting target DNA into bacterial or mammalian host cells, expressing the encoded proteins, and purifying them from cellular systems. Widely used as host, Escherichia coli (E. coli) plays a key role in recombinant protein production. There have been various approved therapeutic proteins produced in E. coli, contributing to the low cost. Despite these advantages, the production process is complex and requires strict control over key indicators such as host residuals and process impurities. BRC Bio offers quality testing for E. coli and plasmid products, meeting the requirement of gene therapy, gene-modified cell therapy, vaccine, nuclear acid drug etc.

Biosafety Strategy for Cell and Gene Therapy

Recombinant Protein

Unprocessed Bulk and Lot Release Testing

Following the requirement in medicine registration regulatory, a series biosafety testing activities constitutes recombinant antibody product lot release testing which ensures the purify and safety of antibody medicine in clinical application.

To ensure the biosafety and quality of antibody products for the patients who use the medicine, BRC Biotech provides the full-validated lot release testing services for your products, including microbial contamination detection, adventitious virus detection, purity analysis, product impurity detection, etc.

GMP-compliant testing system

BRC Solutions for Product Specific Qualification

In both ICH 02 and the Chinese Pharmacopoeia 2020, Product-related specificity of testing methods are required to be fully Qualified. At least three batches of antibody products should be used for the product specific qualifica- tion before go to market, to evaluated the validated methods is appliable for the dedicated products under com- mercial process.
