Empowered by GenScript’s TurboCHO™ expression system, our high throughput gene to antibody service enables the fastest “Gene to Target” delivery. From sequence to purified antibody, in as short as 10 business days, TurboCHO™ HT cost-effectively expedites the screening of therapeutic targets. Moving along the discovery workflow, the TurboCHO™ Express service provides a better solution for therapeutic lead expression and optimization and diagnostic biomarker discovery. Finally, once the lead is identified, our TurboCHO™ HP stable expression service is designed to support the flow of drugs into clinical evaluation or diagnostic assay development. By implementing an effective mitigation strategy through gram levels of antibody production while keeping a high-quality standard based on comprehensive QC specs, TurboCHO™ HP provides a leading-edge on candidate selection.
Antibody/Protein Therapeutics
Diagnostic
"CHO cells" or Chinese Hamster Ovary cells have a long history as tools for the generation of biological therapeutics (i.e. monoclonal antibodies, enzymes, cytokines, and hormones). CHO cell-derived monoclonal antibodies have been approved to treat a broad range of indications, including cancer, multiple sclerosis, asthma, HIV, and neuroblastoma. Several favorable properties have driven CHO cells' increased use in bioprocessing, including their resilience to growth conditions, resistance to viral infections, and high protein synthesis capacity. Significantly, protein-processing by CHO cells more closely conserves the post-translational modifications (e.g., glycosylation) and folding found in human proteins.
On top of that, consistent use of a specific cell expression system across the early and late biotherapeutic protein development stages is critical. For example, the use of CHO transit expression in therapeutic monoclonal antibody development expedites the availability of smaller quantities of antibody candidates, ideal for preliminary in vitro testing. Higher-yield stable CHO expression of lead recombinant monoclonal antibodies is a recommended path towards later preclinical stages. This approach increases the probability that candidates for pharmacological and toxicological characterization conserve established glycosylation patterns supporting IND and therapeutic development.
