Adopting next-generation sequencing (NGS) in your lab is now simpler than ever before with industry-leading speed and affordability, with the flexibility to do multiple sequencing applications on a single system.
Whole-genome sequencing offers important new opportunities for the discovery and characterization of viral, bacterial, and fungal organisms. For researchers characterizing the genomic structures of microbes, de novo sequencing and assembly of genomes is an important step. These basic research projects require deep coverage across the genome and high-quality data. Ion Torrent semiconductor sequencing has revolutionized de novo sequencing for microbial research. By democratizing sequencing through a fast, simple, affordable system that is designed to deliver accurate results in less than a day, more and more sequencing projects that were previously unattainable due to budget or time constraints are now feasible. With 400-base pair sequencing on the Ion S5 System, and the Ion PGM™ System with Ion Hi-Q™ chemistry, sequencing assembly metrics are better than ever, with up to a 90% decrease in indel error rates for microbial sequencing (Figure 1), giving you a fast path to whole-genome sequencing.

Template preparation for 200-base read fragment libraries was performed using the Ion PGM™ Template OT2 200 Kit. Indel error rate per 100 kb analysis performed with SPAdes 3.1 delta-score filter.
The Ion Xpress Plus Fragment Library Kit provides rapid and flexible enzyme-based library construction in as little as 2 hours for gDNA and amplicon libraries, with significantly higher yields and lower bias than other library construction techniques.
The MuSeek™ Library Preparation Kit provides a fast and simple transposon-based method for preparing high-quality genomic DNA libraries for Ion Torrent sequencing. The kit utilizes MuA transposase for fragmentation and simultaneous tagging of the target DNA, enabling library construction in as little as 80 minutes.
Torrent Suite™ Software provides the tools that take you from raw sequence data to informative results, including optimized signal processing, base calling, sequence alignment, and variant analysis. Post run, sequencing data are available for download with a simple right-click. Reports are also easily browsed, with expandable analysis plots and straightforward tables that summarize key results to help ensure that sequencing runs are of high quality.
By expanding the functionality of the current on-board software, plugins offer a powerful means to manage a full range of additional applications and analyses. Torrent Suite Software allows you to customize your analysis at the end of each run through the use of different plugins—de novo assembly, resequencing, and metagenomics applications are included in the software—which are available for download in the Torrent Browser Plugin Store.
DNASTAR - SeqMan NGen software enables you to assemble reads from any major next-gen sequencing platform, including Ion Torrent platforms, with just a few simple steps.
