Our linearisation workflow is designed for maximal integrity and reproducibility. Plasmid linearisation is performed using sequence-specific enzymes that ensure precise cutting at designated sites. This process generates linear pDNA that functions as a clean and reliable starting material for transcription. Each custom construct is verified post-linearisation by advanced electrophoresis methods and analytical controls to confirm structural integrity, maximum homogeneity, and the absence of residual enzymes or incomplete digestion.
The benefits of using highly pure linearised plasmids as templates in transcription include increased transcriptional accuracy and higher mRNA yields. This is particularly critical in therapeutic applications where the quality and reproducibility of the final molecule must meet strict safety and efficacy standards. Whether for gene therapy, vaccine development, or cell-based treatments, linear DNA remains a cornerstone in high-performance mRNA manufacturing workflows.
As an established manufacturer of plasmids, PlasmidFactory supports firstly advanced purification of plasmid and minicircle DNA and secondly DNA linearisation. All services are performed under stringent quality monitoring, with optional documentation packages for regulatory submissions.
Using proprietary purification steps, we deliver linear plasmid DNA of exceptional quality – free from endotoxins, genomic DNA, and RNA contamination. The result is a highly functional template ready for use in transfection or further downstream processing.
Additionally, we offer specialized services for minicircle DNA, an innovative alternative to traditional plasmids for specific applications, owing to their smaller size and lack of bacterial backbone sequences. These properties lead to improved expression and lower immunogenicity, making them ideal for non-viral gene delivery systems and therapeutic use.
Each plasmid DNA batch can be linearised on demand, with full QC documentation including gel electrophoresis profiles and optionally sequence confirmation. By providing customizable linear constructs, we ensure flexibility for clients in research, development, and clinical production settings.
Whether you’re developing new biologics, optimization of a vector for cell and gene therapy, or scaling up production of mRNA, PlasmidFactory delivers the tools and expertise needed for reliable and scalable results. Trust us to be your partner in delivering safe, reproducible, and highly pure nucleic acids.
