Mammalian Cell Culture Services

At Rodon Biologics, mammalian cell culture is a fundamental technology for producing complex biologics, including monoclonal antibodies, multispecific antibodies and recombinant proteins. Unlike microbial systems, mammalian cells provide the intricate cellular machinery necessary for correct protein folding, glycosylation, and post-translational modifications, ensuring biologics closely mimic their natural human counterparts. Leveraging state-of-the-art technologies and over two decades of expertise, we design scalable, high-yield processes tailored to the unique demands of each biosynthetic project.

Our Mammalian Cell Culture Expertise

Rodon Biologics specializes in optimizing mammalian cell culture systems for both research and commercial-scale production. Our expertise spans multiple mammalian expression platforms, allowing us to develop processes that maximize productivity while maintaining product quality and regulatory compliance.

Mammalian Transient and Stable Expression and purification

We offer both transient and stable mammalian expression systems to support the rapid and scalable production of recombinant proteins and biologics. Our capabilities range from small-scale production for research applications to in-vitro studies and in-vivo testing, ensuring a reliable supply for early-stage development.

• Transient Expression: Rapid protein production using transient transfection in HEK293 or CHO cells, providing fast turnaround times for early-stage research, assay development, and screening applications.
• Stable Cell Culture & Hybridomas: Cultivation of stable cell lines and hybridomas for sustained antibody/protein expression or for cell expansion when the cells themselves are the product of interest.
• Small-Scale Protein Production: Scalable expression and purification of proteins from transient or stable cell lines to support research, in-vitro studies, and preclinical in-vivo testing.
  
  

Cell Line Development & Optimization

The foundation of a successful mammalian cell culture process begins with a robust and productive cell line. At Rodon, we employ genetic engineering and screening techniques to establish high-yield cell lines tailored to your specific biologic.

• Cell Line Engineering: Utilizing transfection with expression vectors to enhance cell productivity, stability, and recombinant protein expression efficiency.
• Clone Screening & Selection: High-throughput screening to identify the most productive clones with optimal growth and expression characteristics.
• Cell Line Characterization: Comprehensive evaluation of cell growth, productivity, and genetic stability to ensure long-term consistency.
  
  

Upstream Process Development

We optimize mammalian cell culture conditions to enhance cell viability, maximize protein expression, and ensure reproducibility at scale. Our customized strategies support robust and cost-efficient production of complex biologics.

• Media & Feed Strategy Optimization: Screening and selection of commercially available media and feed regimens to sustain high cell densities and maximize yield.
• Bioreactor Process Optimization: Fine-tuning of critical parameters, such as pH, temperature, oxygenation, and agitation, to optimize cell growth and productivity.
• Process Scale-Up: Seamless transition from small-scale cultures to pilot and commercial-scale bioreactors, ensuring process consistency and regulatory compliance.
  
  

Downstream Processing & Purification

After cultivation, efficient product recovery and purification are essential to obtain biologics of the highest quality. Rodon Biologics employs advanced purification methodologies to ensure high purity, activity, and stability.

• Cell Harvesting & Clarification: Effective separation of cells and debris using centrifugation, depth filtration, or microfiltration.
• Chromatographic Purification: Multi-step purification using affinity, ion-exchange, and/or hydrophobic interaction chromatography to achieve high purity and yield.
• Final Processing & Formulation: Ensuring stability and bioactivity of the purified product, including buffer exchange, concentration, and spray-drying if required.
  
  

Analytical Support & Quality Assurance

To guarantee process robustness and product integrity, we provide comprehensive analytical support throughout development and production.

• In-Process Monitoring: Real-time monitoring of critical parameters such as cell viability, metabolite consumption, and protein titer.
• Protein Characterization: Extensive biochemical and biophysical analysis, including HPLC, SDS-PAGE, ELISA, and glycosylation profiling.
• Regulatory-Grade Quality Control: Ensuring batch-to-batch consistency and compliance with industry standards and regulatory guidelines.
