Plasmid preparation: High-Quality DNA for Reliable Results

 

Scale Up with Larger Plasmid Prep Options

 

The pure preparation of plasmid starting materials can be time-consuming and frustrating, especially when your focus should be on the experiments that truly matter. Why not try a new approach: outsource your plasmid preparation and order a scale that suits your experimental needs.

Our plasmid preparation services provide highly purified, reliable plasmid DNA suitable for research, development, and diagnostic applications. Whether you need material for cloning, transfection, sequencing, screening, or advanced downstream analyses, we offer preparation scales tailored to your project.

Choose from Midi, Maxi, Mega, or Giga preps and benefit from high yields, excellent purity, and complete quality control. For sensitive applications, we also offer endotoxin-free, animal-origin-free, and sterile preparation options. Plasmid linearization is also available on request.

If you would like to receive a quote for a plasmid preparation project, please provide us with your vector information, the desired preparation scale, and any specific quality requirements (e.g., endotoxin-free, sterile, animal-origin-free.).

 
 

Our Plasmid Preparation service includes:

 

  • Project Intake & Feasibility Assessment
    We evaluate all relevant details — plasmid size, host strain, resistance markers, culture requirements, and intended downstream use — to identify the optimal purification strategy for your project.
  • Bacterial Cultivation & Plasmid Production
    Standardized cultivation procedures and selective antibiotic conditions ensure stable plasmid propagation and high DNA yield. Upon request, we can work with customer-provided starter material or prepare glycerol stocks for future projects.
  • Purification & Quality Optimization
    Depending on the preparation scale, we use validated purification methods including purification via Magnetic Beads and endotoxinreduction workflows. These processes guarantee high purity, minimal genomic DNA contamination, and excellent plasmid integrity.
  • Delivery & Documentation
    Your plasmid DNA is delivered in water or buffer, accompanied by a comprehensive quality report, analytical results, and any available sequence information.

 

 

  • Quality Control & Verification
    Each plasmid preparation undergoes rigorous QC testing, including:
    • Spectrophotometric (concentration and purity)
    • Optional: Sanger sequencing (free of charge), restriction digest analysis, or additional testing
    This ensures reliable, reproducible, and application-ready DNA.
  • Strict Confidentiality
    All critical steps — from cultivation to purification and QC — are carried out exclusively within our secure Eurofins DNA facilities. Your samples and data remain protected at all times.
  • LongTerm Expertise in Plasmid DNA Production
    Our experienced laboratory teams work with plasmids of all sizes and complexities and continuously optimize our methods to provide consistently high-quality results.
 

Eurofins Genomics offers a variety of plasmid preparation services to cover individual needs:

 

Scale Culture volume Yields*
Midi Prep 50ml-100ml 15µg-50µg
Maxi Prep 100ml-250ml 100µg-500µg
Mega Prep 0.5l-2.5l 500µg-2.5mg
Giga Prep 2.5l 2.5mg-10mg
Giga Prep Plus 5l 5mg-20mg

 

*These yields only apply for high-copy plasmids. For low-copy plasmids a re-prep may be required.

 

Turnaround times

 

Turnaround time (TAT) for plasmid preparations depend on the availability of your plasmid.


Production can begin only after we have received your plasmid. If sequencing of the plasmid is required as part of the quality control (QC), production will start only after we have completed the incoming QC, which typically includes a single Sanger DNA sequencing read.


Once the plasmid passes QC, the standard TAT is approximately 10 days. An express option is available starting from 5 days. For large batch orders, please contact us in advance to check for available production slots before placing your order.
