GMP Plasmid Manufacturing Process

The manufacturing process involves screening for optimal growth, E. coli master and working cell bank preparation, shaking flask or high-density fermentation, harvesting lysis, chromatographic purification, quality monitoring and process control. The types of plasmids we produce include the viral vector (Retro, Adeno, AAV, HSV, VLP), and non-viral vector (DNA, RNA, EP, GGun, Lipo).

Strain Selection and Genetic Engineering

At Creative Biolabs, the journey of plasmid manufacturing begins with meticulous strain selection and genetic engineering. This stage is crucial for ensuring the plasmid's integrity and functionality. By employing advanced genetic manipulation techniques, Creative Biolabs can enhance plasmid stability and optimize gene expression, which are essential for successful therapy outcomes.

Cell Bank Preparation

The creation of robust E. coli master and working cell banks forms the foundation for scalable plasmid production. Creative Biolabs focuses on genetic stability and viability, ensuring that each cell bank can consistently produce plasmids with the desired qualities across various batches.

Fermentation

Creative Biolabs has developed capabilities to conduct fermentation on scales ranging from small shaking flasks to large high-density systems, accommodating production volumes from 10 to 1,000 liters. This flexibility allows the adaptation of production volumes to the project-specific demands of clients, maintaining optimal growth conditions throughout.

Harvesting and Lysis

Following fermentation, the plasmid-containing bacterial cells are harvested. Creative Biolabs employs the alkaline lysis method, among other techniques, to ensure the efficient release and high quality of plasmid DNA, crucial for subsequent downstream applications.

Purification Process

The purification stage is tailored to the type of plasmid being produced, using chromatographic techniques and other methods to remove impurities effectively. This step is vital to achieving the high purity required for medical applications, ensuring that each plasmid batch meets stringent quality standards.

Quality Control and Assurance

Creative Biolabs implements a comprehensive quality control and assurance program, employing various assays such as UV Spectrophotometry and kinetic turbidimetric LAL. These measures are critical to verify the purity, potency, and safety of the plasmid DNA, adhering to global manufacturing standards.
