Ion Torrent

In August 2010, Life Technologies announced a definitive agreement to acquire Ion Torrent for $375 million in cash and stock, with an additional $350 million contingent on meeting certain milestones, a deal that closed in October 2010. This acquisition integrated Ion Torrent's technology with Life Technologies' commercial reach and expertise in sample preparation and informatics. Dr. Rothberg continued to lead the Ion Torrent team post-acquisition. Subsequently, Thermo Fisher Scientific acquired Life Technologies, bringing the Ion Torrent brand under its portfolio.

Ion Torrent's core business revolves around providing next-generation sequencing (NGS) systems, reagents, and software to a diverse client base that includes hospital and health care facilities, higher education institutions, and biotechnology companies. The company's business model is based on the sale of sequencing instruments and the recurring revenue from proprietary semiconductor chips, reagents, and analysis software.

The company's key technology is ion semiconductor sequencing, which directly translates chemical information from DNA into digital data. Unlike optics-based methods that detect light, Ion Torrent's systems use a semiconductor chip to detect the hydrogen ions released during DNA polymerization. When a nucleotide is incorporated into a DNA strand, it releases a hydrogen ion, causing a pH change that an ion-sensitive sensor detects as a voltage signal. This process avoids the need for lasers, cameras, and light, resulting in a simpler, faster, and more cost-effective sequencing workflow. The technology leverages the massive investment in the semiconductor industry, allowing it to benefit from Moore's Law. Products include the Genexus System, which automates the entire workflow from specimen to report in a single day, and the Ion GeneStudio S5 Systems, which offer scalable throughput for various research needs. The technology supports numerous applications, including oncology research, inherited disease analysis, infectious disease studies, and human identification for forensics.
