Biomanufacturing
Discover our R&D, HQ and GMP grade plasmid bioproduction solutions, as well as our process development expertise tailored to the requirements of each project.

R&D grade plasmid bioproduction
A fast and flexible solution! From µg quantities to hundreds of mg, we tailor production to your specifications, supporting every stage of your development programmes.
RD-Biotech can supply 10 mg batches in 3 days and 100 mg batches in 6 days!
- EndoFree quality: we guarantee a residual endotoxin level below 0.1 EU/µg of DNA
- High production capacity: from a few milligrams to several grams per plasmid. Quantity guaranteed!
- Very short lead times
- Plasmid production from DNA, bacterial plates or glycerol stocks
- Pre-production controls
- Final quality controls included at no additional cost: spectrophotometric quantification and restriction enzyme digestion analysis
- Predominantly supercoiled form
- Batch-to-batch consistency
- Secure storage available for recurring plasmid production
- Process adaptation for low-copy plasmids or plasmids prone to recombination
- Bacterial transformation
- Adjustment to the required DNA concentration
- Aliquoting
- Sequencing analysis — single- or double-stranded, insert-only or full-plasmid
- Supercoiled DNA percentage measurement
- Bacterial endotoxin testing using the LAL (Limulus Amebocyte Lysate) assay
- Sterility testing
- Other requirements: contact us
- Transfection or co-transfection of mammalian cells
- In vitro transcription
- Recombinant protein and antibody production
- In vivo studies involving animal injection
- Preclinical studies
- Toxicology studies
- Research and development applications
HQ grade plasmid bioproduction
High-quality plasmid manufacturing for clinical applications, including use as raw materials in cell and gene therapy programmes involving therapeutic mRNA, AAVs, lentiviruses, CAR-T cells, retroviruses and more.
- Full traceability and project-specific documentation
- Creation of a bacterial cell bank for each plasmid
- Storage of the bacterial bank in a secure area
- Production of only one plasmid per High Quality-grade manufacturing campaign in a dedicated room
- Large-scale antibiotic-free culture
- An animal-free production process
- Additional steps to ensure maximum product purity, in line with quality standards compatible with raw materials intended for GMP manufacturing
- Quality controls tailored to the sponsor’s specifications and applicable regulations: percentage of supercoiled DNA, bacterial DNA, residual host-cell proteins, bacterial RNA and endotoxins (list of quality controls)
- Optional plasmid linearisation for mRNA preparation by in vitro transcription
GMP grade plasmid bioproduction
With its GMP manufacturing facility, RD-Biotech can supply GMP grade plasmids as starting materials for innovative therapeutic applications, including cell therapy, gene therapy, and messenger RNA-based therapies and vaccines.
