GMP Plasmids
As a crucial starting material for many advanced therapies, plasmids are one of the most important tools in the field of cell and gene therapy (CGT). The rapid growth of the CGT field has stimulated large demand of plasmid production. From adenovirus, adeno-associated virus, lentivirus viral vectors to chimeric antigen receptor (CAR) cell therapy, plasmids are a vital first step.
​
At uBriGene, our expert specialists can provide custom plasmid productions that fit your project specifications. We offer integrated manufacturing platforms and quality control systems for plasmid productions from milligrams to gram scales. Our systems allow for ease of scale-up and mass-productions for any quality of plasmids your project requires; from research-grade to non-GMP/GMP-like to full GMP grade plasmids.
Production Workflow
uBriGene’s GMP plasmid production process includes upstream fermentation and downstream purification processes. Our Isolated and separated plasmid production floor contains fermentation tanks of up to 200L capacity. Single use fermenters can also be used to further reduce risk of cross-contamination. Our high-density fermentation process can yield plasmid concentrations of >1g/L. Alkaline lysis allows for full parameter control of downstream plasmid purification process with ease to scale up linearly.
Our two-step column chromatography purification allows for time and cost-efficient optimizations. With the same quality standard as a three-step purification process, our in-house manufactured resin provides ~85% cost reduction in plasmid production.
