The company Pyrosequencing AB in Uppsala, Sweden was founded with venture capital provided by HealthCap in order to commercialize machinery and reagents for sequencing short stretches of DNA using the pyrosequencing technique. Pyrosequencing AB was listed on the Stockholm Stock Exchange in 1999. It was renamed to Biotage in 2003. [7]
454 Life Sciences was a biotechnology company based in Branford, Connecticut that specialized in high-throughput DNA sequencing.It was acquired by Roche in 2007 and shut down by Roche in 2013 when its technology became noncompetitive, although production continued until mid-2016.
The 454 DNA sequencer was the first next-generation sequencer to become commercially successful. [10] It was developed by 454 Life Sciences and purchased by Roche in 2007. 454 utilizes the detection of pyrophosphate released by the DNA polymerase reaction when adding a nucleotide to the template strain.

A parallelized version of pyrosequencing was developed by 454 Life Sciences, which has since been acquired by Roche Diagnostics. The method amplifies DNA inside water droplets in an oil solution (emulsion PCR), with each droplet containing a single DNA template attached to a single primer-coated bead that then forms a clonal colony.
This method should not be confused with "sequencing by synthesis," a principle used by Roche-454 pyrosequencing (introduced in 2005, generating millions of 200-400bp reads in 2009), and the Solexa system (now owned by Illumina) (introduced in 2006, generating hundreds of millions of 50-100bp reads in 2009)
Rothberg lost control of 454 Life Sciences by 2007. [3] The company was acquired by Roche Diagnostics in 2007 for $140 million then closed down by Roche in 2013 after other approaches to sequencing rendered the underlying technology noncompetitive. [12] [2] In 2004, Rothberg founded RainDance Technologies, which used droplet-based microfluidics ...
