Plasmid DNA Preparation

For years, Synbio Technologies has provided comprehensive plasmid DNA preparation services to our customers from research institutes and biotechnology and biopharmaceutical industries. We have developed and perfected a manufacturing pipeline designed to meet the requirements of the Good Manufacturing Protocol (GMP). These requirements guarantee both in-process controls and final product quality control, to ensure that the highest quality product will be generated. All plasmids we manufactured are free of animal-derived materials and can contain low levels of endotoxin (<0.005EU/μg, on request). This process is designed to meet our customers’ diverse downstream applications such as transfection, antibody preparation, vaccine and gene-therapy research. In addition to our services, we offer complete and detailed documentation that allows us to track and monitor the whole manufacturing process from start to finish. Throughout this process our project management team will monitor the whole operation process to ensure on-time delivery. This process culminates with extensive quality control assays including sequence verification, restriction enzyme digestion and endotoxin analysis. After passing our strict quality control assays, we guarantee the quantity and quality of our delivered products. The result is high quality plasmid DNA ready to ship to our customers all over the world. To protect your intellectual property, we are willing to sign an agreement or contract if deemed necessary. We guarantee to protect our customers’ benefits and their products. Dispensing is also available on your request. Additional expense may be charged depending on the quantity and other requirements.

Note: Synbio Technologies provides upstream services of plasmid preparation such as gene synthesis and subcloning into both commercial and custom vectors. This allows us to offer a unique approach to satisfy all our customer’s requests. Additionally, if you wish to provide the plasmid template, you will need to prepare over 100 ng DNA sample (diluted with ddH2O or TE buffer), colonies (fresh) or bacteria stored in glycerol.

Quality Control

Synbio Technologies plasmid preparation service focuses on quality. We have strict quality control which can increase quality stability and reduce batch difference to satisfy customers’ high-quality needs.

Case Studies

Application Grade Plasmid DNA Preparation

Day 1: Bacteria were transformed by target plasmid DNAs and grown on LB agar plates with proper antibiotics.
Day 2: Bacterial Colonies were selected and cultured in LB medium with proper antibiotics.
Day 3: Mini-prepped plasmid DNAs, followed by restriction enzyme analysis to verify the DNA sizes. In addition, liters of bacteria cultures were inoculated for a large-scale preparation of plasmid DNAs.
Day 4: Bacteria were harvested and the plasmid DNAs were purified.
Day 5–7: Quality Test Results

1. Endotoxin Test: Negative results will be not indicated.

endotoxin test

2. Sterility Test: No bacterial colony is detected after 48 hours culturing in LB medium.

3. Restriction enzyme digestion: correct DNA sizes
4. Sanger sequencing: correct sequence in specified regions.

Day 8: DNAs were formulated, dispensed, labelled, and delivered.
