GS FLX+ System : High Throughput Sequencer
To find out more about using this technology in your research contact us.
Sanger-like read lengths - the power of next-gen throughput. The complete sequencing workflow of the GS FLX and GS Junior Systems comprise of four main steps, leading from purified DNA to analyzed results. These basic steps include:
- Generation of a single-stranded template DNA library:
- Emulsion-based clonal amplification of the library:
- Data generation via sequencing-by-synthesis:
- Data analysis using different bioinformatics tools:

- De Novo Sequencing: Whole Genomes of Humans, Plants, Yeasts, Fungi, Bacteria, Viruses, BACS etc.
- Resequencing: SNPs, InDels, Somatic Mutations
- Transcriptome Analysis: cDNA, small non coding RNA, microRNA
- Epigenetic Changes: DNA Methylation Patterns
- Metagenomics: Analysis of Environmental DNA
- Paleogenomics : Ancient DNA
2-4µg of double stranded DNA in more than 10µl volume is required.Ideally DNA size should be larger than 2kb. If your DNA is 500bp long or less, then about 3µg in more than 10µl volume is necessary. The DNA should be suspended in H2O or 1X TE.
Provide the DNA at a concentration > 300ng/µl and A260/280 ratio of approximately 1.8.
An image of DNA sample(s) run on a 1-2% agarose gel is requested to assess quality of incoming DNA. We will further assess the quality using Bioanalyzer and Nanodrop.
De novo sequencing requires 20X average genome coverage. Resequencing and mapping projects require 15X average coverage.
