Hillgene is specialized in the provision of integrated CDMO solutions for cellular therapy products, has established a GMP manufacturing platform for nucleic acid products, and therefore, can provide high-quality CDMO services for plasmids to clients with various demands.

*Note: Hillgene established QC methods corresponding to different technology platforms, with QC methods including but not limited to above items.
Advantages of our plasmid system:
• An independently developed four-plasmid system with kanamycin-resistance gene
• A system with the capability of sustained optimization
• Plasmid sequences are traceable, compliant with requirements, and efficient
• Extensive experience in successful IND submissions
• CAR-T cell samples for clinical use are currently manufacturing and in use
• 2-5 folds higher titers after using our plasmid system from the comparison in several projects
Advantages of our plasmid manufacturing:
• Free of antibiotics throughout the manufacturing process
• Plasmid production and bank creation in separate workshops
• Complete isolation between non-sterile and sterile areas
• Dispensing final products using an isolator
• Completed CTD dossiers for packaging plasmid (for lentiviral vector), reducing the submission preparation time by 3-4 months, with INDs of a few products granted preliminary approval and currently in phase I of clinical study
