Plasmid DNA for Biopharma

The demand for high quality plasmid DNA has increased vastly in response to rapid advances in its use in gene therapy and vaccine production. New applications like mRNA based vaccines or gene therapy treatment all require plasmid DNA as an important starting material.

Biopharma applications

Our products for Biopharma

MACHEREY-NAGEL offers innovative solutions for cell lysis, clarification and plasmid purification to constantly deliver high yields with minimal endotoxin contamination. To ensure maximum flexibility, we offer all components needed for plasmid purification with our endotoxin kits as standalone products. For more information, please have a look at our flyer and in the listings below.

Endotoxins

Endotoxins are heat-stable toxins associated with the outer membranes of certain gram-negative bacteria. Chemically they are Lipopolysaccharides (LPS). In large quantities they produce hemorrhagic shock and severe diarrhea; smaller amounts cause fever, altered resistance to bacterial infection, leukopenia followed by leukocytosis, and numerous other biologic effects.

Endotoxins can lead to the release of cytokines such as
  • Tumor necrosis factor
  • activation of coagulation system
  • Anaphylatoxin C5a and C3a
  • Myocardial depressant factor
  • Platelet-activating factor
  • Beta - endorphins
  • Bradikinin
  • Histamine

Automation for Biopharma

NucleoBond Xtra Midi EF, for endotoxin-free DNA

Medium and large-scale plasmid DNA preparations for transfection play an important role in many fields of research as well as the pharma and biotech industry. Obtaining sufficient amounts of transfection-grade plasmid DNA is more important than ever.

Anion exchange columns are successfully used to purify large amounts of highly pure plasmid DNA and remain the tool of choice for large-scale, high purity plasmid isolation. While providing significant advantages, most anion exchange columns are also slow and labor intensive. 

To tackle these issues, MACHEREY‑NAGEL and Andrew Alliance have combined their strengths to automate NucleoBond Xtra Midi and NucleoBond Xtra Midi EF, the fastest anion exchange column on the market with Andrew+, a highly flexible and dexterous liquid handler robot. The protocol enables completely automated purification of more than 2400 μg of transfection-grade plasmid DNA per run (6 preps with >400 µg each).

Our automation partner for plasmid DNA

AAV - Adeno associated viruses as DNA shuttles for gene therapy

The vector of choice for gene therapy is the adeno-associated virus (AAV). AAVs have an excellent safety profile and cannot replicate independently. Another safety feature of AAVs is that they cannot integrate into the host genome.

MACHERY-NAGEL offers a wide range of kits for the development and research of AAVs that meet the specific requirements of our clients.

From plasmid DNA to mRNA vaccines - from construct to lifesaving medicine

Vaccines offer a safe way to immunise the population against contagious diseases. As the global population increases, so will the demand for rapid development of effective vaccines against sudden disease outbreaks.

mRNA vaccines offer superior speed and flexibility in combatting new diseases because they are highly adaptable and cost-efficient to develop. Once an antigen of a disease has been identified, the genetic information can be adapted and incorporated into plasmid vectors, which can then be amplified by bacteria. After sufficient amplification, these vectors can be harvested and the genetic information can be transcribed in vitro into mRNA. Following further purification and encapsulation of the mRNA in lipid nanoparticles (LNPs), it is ready to be used as a vaccine.

MACHEREY-NAGEL offers a broad portfolio of plasmid DNA extraction kits for every stage of vaccine development. Whether it's the initial testing or the actual production, our products provide plasmid DNA of the right purity at the right price!
The same goes for the purification of mRNA from in vitro transcriptions!
