TurboCHO™ Expression System

Introduction

The TurboCHO™ expression system is a high-performance Chinese Hamster Ovary (CHO) platform designed to produce recombinant proteins and monoclonal antibodies (mAbs) with enhanced yield, speed, and quality. Leveraging advanced cell line engineering, optimized culture conditions, and streamlined production workflows, TurboCHO™ accelerates biopharmaceutical development while ensuring scalable and cost-effective manufacturing.

Mechanisms of TurboCHO™ Expression

• Transfection
  Transfection is achieved using plasmid DNA encoding target proteins, introduced via electroporation or chemical reagents like polyethyleneimine (PEI).
• Gene Expression and Protein Synthesis
  • Promoter: Strong viral promoters, such as CMV and EF-1α, ensure robust transcription.
  • mRNA Stability: Optimized 5' and 3' untranslated regions (UTRs) extend mRNA lifespan, enhancing translation efficiency.
  • Ribosome Optimization: Genetic modifications improve ribosome efficiency for faster and more accurate translation.
  • Codon Usage and Protein Folding: Codon optimization aligns with the cellular tRNA pool to prevent ribosome stalling, while molecular chaperones (e.g., BiP, PDI) ensure proper protein folding.
• Post-Translational Modifications
  • Glycosylation: Engineered to perform human-like glycosylation, ensuring compatibility with human biology.
  • Protein Folding and Assembly: Chaperones and folding enzymes minimize misfolded proteins and aggregation, improving product quality.
• Protein Secretion and Yield Optimization
  Correctly folded proteins are secreted into the culture medium for downstream purification. Optimized fed-batch culture systems and selective gene amplification (e.g., DHFR system) sustain high productivity.

Applications of TurboCHO™ Expression

• Research and Diagnostics: TurboCHO™ enables rapid generation of high-quality proteins for structural biology, functional assays, and diagnostic kits.
• Antibody Production: Production of purified antibody products (e.g., IgG, Fab, scFv, VHH, bispecific antibodies, etc.), Large-scale production is possible.
