800 bp Read Length For Amplicon Sequencing Is Not Science Fiction

Amplicon sequencing with Roche GS JuniorAbout a year ago my colleguage Regina reported about the new possibilities of using the MiSeq system for amplicon sequencing (16S Amplicon Experiments: Which Platform to Choose?). Now, one year later still everything is true about the advantages of amplicon sequencing using the MiSeq (e.g. lower cost/base).

The main advantage of the Roche system are the long reads that are highly valuable for some applications. By ligating appropriate sequencing adaptors we can currently deliver average read length of up to 700 bp when using the GS FLX+ pipeline. Further improvements regarding the read length can be expected with the launch of a new amplicon pipeline from Roche for the Roche GS FLX+ system (planned for summer 2013).

And beside the ultra long reads on the GS FLX+ system there are still some advantages of amplicon sequencing using the GS Junior system compared to other technologies:

+ short turnaround time (starting from 5-10 working days)

+ competitive pricing

+ moderate to long reads (350 – 450 bp)

+ sufficient data output for all projects with a medium size of samples (e.g. up to 24)

Spring Special – Amplicon Sequencing

  • Would you like to detect variances down to a frequency of 0.1% in your PCR sample?
  • Are you interested in a short turn around time?
  • You need primers for your amplicons?


Amplicon sequencing is still under discussion. Which technology is most suitable? In one of our latest blog posts we discussed this issue as well. For this years spring special we therefore decided to create a new NGS Favourite – a one stop solution for Amplicon sequencing. By sequencing your amplicons on the GS Junior we will be able to deliver the data in a short turnaround time while you will still profit from the long reads the FLX chemistry provides. Furthermore you will get comprehensive bioinformatic data that will be able to answer already questions like: how many clusters were obtained or what is the homology of each read compared to the representative read. This data will help you for example to analyse metagenomes in your environmental samples like soil, water or gut.

Additionally we as a service provider for oligonucleotide synthesis, gene synthesis, custom DNA sequencing and NGS are able to offer you primers for free for your amplicon sequencing approach if you order our Spring Special.

Contact us if you are interested in a spring special quote or read more on our website. This offer is valid until 30.06.2012.
