CD Genomics provides complete plasmid DNA sequencing service, and our improved bioinformatics pipelines are available to perform de novo assembly with no reference required.
Plasmids are perceived as mobile genetic elements that exist extra-chromosomally and occasionally carry accessory genes that confer an advantage to their host in its ecological niche. They are thus thought to play an important evolutionary role in microbial communities by laterally introducing genes and traits into microbial genomes. Plasmids are important vehicles for rapid adaptation of bacterial populations to changing environmental conditions. The genetic variation generated by plasmid carriage within populations ensures the robustness towards environmental change. Plasmid-mediated gene transfer plays an important role not only in the mobilization and dissemination of antibiotic resistance genes but also in the spread of degradative pathways and pathogenicity determinants of pathogens.
Despite their importance, technical obstacles still limit the plasmid study. Plasmid DNA sequencing is rapidly becoming a standard approach to increase our understanding of the genetic diversity and evolutionary history of plasmids. Complete plasmid genome sequencing refers to the process of determining the entire genetic sequence of a plasmid. It not only helps to define the molecular events that took place during the evolution of these plasmids, but also give us a more complete overview of the enormous collection of accessory genes encoded on plasmids. And comparative plasmid sequence analysis has provided insights into the evolution of plasmids and their relatedness, their modular structure and the existence of hot spots for the insertion of accessory genes.
Plasmids exhibit significant heterogeneity in terms of size and complexity, often featuring high GC content, intricate structures, or large repetitive segments. These characteristics have historically rendered traditional Sanger sequencing methods cost-prohibitive, prone to high failure rates, and characterized by relatively slow processing.
|Whole Plasmid Sequencing (NGS)
|Utilizes Next-Generation Sequencing (NGS)or Long Read Sequencing technologies
|Suitable for shorter fragments (up to 1,000 bp)
|Can sequence entire plasmids, regardless of size or complexity
|Sanger Sequencing can involve extended processing times and is particularly suited for small-scale projects.
|In contrast, Whole Plasmid Sequencing using NGS technologies provides a swifter turnaround, making it well-suited for high-throughput applications.
|Can be cost-prohibitive for larger plasmids due to multiple sequencing reactions
|Generally more cost-effective, especially for larger plasmids, as it involves fewer sequencing reactions
|Sanger Sequencing is renowned for its exceptional precision and minimal error rates.
|Whole Plasmid Sequencing maintains a high degree of accuracy and incorporates enhanced error correction methods.
|Sanger Sequencing is appropriate for smaller plasmids but may encounter challenges when dealing with larger, intricate, or repetitive plasmid structures.
|Whole Plasmid Sequencing is highly versatile and can accommodate plasmids of various sizes and complexities, rendering it suitable for comprehensive plasmid analysis.
