Penzberg, Germany, 11 December 2012. International study presented at American Society of Hematology Meeting demonstrates the potential of 454 Sequencing Systems to comprehensively characterize an individual’s blood cancer type to guide personalized therapy decisions 2011-05-19 · Background The rapid evolution of 454 GS-FLX sequencing technology has not been accompanied by a reassessment of the quality and accuracy of the sequences obtained. Current strategies for decision-making and error-correction are based on an initial analysis by Huse et al. in 2007, for the older GS20 system based on experimental sequences.

The 454 sequencers will be phased out in mid-2016, and the 454 facility in Branford, Conn., will be closed "accordingly," Roche said in a statement e-mailed to GenomeWeb Daily News.

Roche 454 sequencing can sequence much longer reads than Illumina. Like Illumina, it does this by sequencing multiple reads at once by reading optical signals as bases are added.

It can be used to get large quantities of DNA nucleotide sequence thus a very important tool in genomic sequencing. Has lead to a break through in biotechnology, forensic science, systematics and medical science's fields. The 454 sequencing technology is a high throughput sequencing technology based on large-scale pyrosequencing.

Roche 454 sequencing

Based on next generation 454 Sequencing Systems from Roche, the study aims to characterize selected genes in individuals with a wide range of hematological malignancies. Noticeably, due to the inherent biases of the Roche 454 sequencing approach to produce more frameshifts in A and T rich DNA (Fig. 3), low G+C% genomes sequenced with this platform may have 20% or more genes with frameshift errors whereas the Illumina platform is not affected as much by the G+C% of the sequenced DNA (Fig. 4).
