*ohne Steuern und Versandkosten
Die NucleoBond RS Säule ist eine Anionenaustausch-Säule, die für den halbautomatischen Einsatz in einer Umgebung mit hohen regulatorischen Anforderungen konzipiert ist. Die geschlossene Bauweise der Säule in Kombination mit der Verarbeitung mittels einer Peristaltikpumpe oder eines FPLC-Systems gewährleistet reproduzierbare Ergebnisse bei gleichzeitiger Minimierung des Arbeitsaufwands. Diese Säulen sind in der Lage, hochreine, hochintegrierte Plasmid-DNA in Impfstoffqualität zu isolieren, was zu unserem bisher niedrigsten Endotoxinprodukt führt (≤ 0,01 EU/µg). Je nach Säulengröße und Probenzufuhr können Ausbeuten von 10-200 mg erzielt werden. Um die Vielseitigkeit der Säule zu ergänzen, steht eine Reihe von Clean-up-Protokollen zur Verfügung, die als Support-Protokolle verwendet werden können.

Preparative scale isolation of vaccine-grade plasmid DNA
NucleoBond RS – for high regulatory standards
Modular system for high-quality plasmid purification
- Endotoxin levels ≤ 0.01 EU/μg DNA
- Closed columns for pump or FPLC processing
- Scalable system for up to 200 mg of plasmid DNA
Large-scale plasmid purification for processes with high regulatory standards
In response to rapid advancements in cell and gene therapy as well as vaccine production, the need for top-notch plasmid DNA has increased significantly. Emerging applications, such as mRNA-based vaccines and gene therapy treatments, rely heavily on superior plasmid DNA as a fundamental starting material. One of the most challenging aspects of these applications is dealing with endotoxins – components of cell walls from gram negative bacteria. Here's where MACHEREY-NAGEL’s NucleoBond RS comes into play. By employing the NucleoBond RS workflow, you can achieve endotoxin levels ≤ 0.01 EU/μg DNA, ensuring compliance with stringent regulatory standards. NucleoBond RS columns are designed for large-scale isolation of vaccine-grade plasmid DNA from bacterial cultures, utilizing peristaltic pumps or FPLC systems meeting the highest quality requirements.

Application data – Large-scale plasmid DNA purification
The NucleoBond RS purification workflow enables a straightforward scalability of your plasmid purification
Plasmid DNA was purified from E.coli with the four different sizes of our NucleoBond RS columns. The figure shows the maximum amounts of plasmid DNA achieved per column size.
Plasmids isolated with NucleoBond RS columns show very high structural integrity
The supercoiled form of plasmid DNA is considered to be the desirable form for applications like gene therapy or vaccination. Regulatory standards specify that plasmids have to be present with more than 90 % supercoiled form. These data show that plasmids isolated with our NucleoBond RS columns meet these standards.
Vaccine-grade plasmid DNA with more than 90 % supercoiled form
Technical data from plasmid isolations using our NucleoBond RS columns show endotoxin levels ≤ 0.01 EU/μg DNA, A260/A280 purity ratios between 1.8 – 2.0, and percentages of supercoiled (ccc) form ≥ 90 %.
