454 Sequencing:

Pyrosequencing is a DNA sequencing technique that utilizes enzyme coupled reactions and bioluminescence to monitor the pyrophosphate release accompanying nucleotide incorporation, in real time. The pyrosequencing method was developed by the group of Pal Nyren. With the aim of commercializing the new DNA sequencing technique, Nyren and others founded Pyrosequencing AB in 1997. The technology was licensed  to 454 Life Sciences, which was later acquired by Roche in 2007. 16S DNA amplicon sequencing enables the identification and quantification of bacteria within complex mixtures of PCR amplicons. You can find a detailed description of the technique here .

Ion Torrent PGM sequencing:

The Ion Torrent sequencing platform from Life Technologies employs First PostLight™ sequencing technology (semiconductor technology). The detection of a specific nucleotide on a growing DNA strand occurs inside a well of an Ion Torrent semiconductor chip. The incorporation of the correct base triggers a chemical reaction that releases a hydrogen ion as byproduct, which in turn changes the pH of the solution. The Ion sensor captures voltage change measurements from the direct release of hydrogen ions following DNA polymerization and incorporation events get recorded as digital signals 1 and 0. This technology differs from other sequencing technologies in that no modified nucleotides, no lasers, no optics, no camera, no fluorescence, no enzyme cascade are used.

Illumina library preparation, barcoding, and sequencing:

This service includes DNA/RNA library preparation for Illumina sequencing platform for a variety of starting materials and sample barcoding to allow sequencing of multiple samples per lane. Library preparation workflow includes fragmentation, end repair and 3’ dA addition, adapter ligation, size selection and enrichment. During the enrichment PCR DNA can be barcoded for multiplexing using 8 bp indexes unique to each sample following 5’ or 3’ barcoding strategy.  The barcodes can be added between the downstream bPCR adaptor and the core sequencing library adaptor.

Illumina RNA sequencing:

The service includes total RNA, small RNA or mRNA sequencing for the analysis of gene expression changes, detection of novel transcripts, small RNA discovery, alternative splice sites and cSNPs. Illumina is the only platform that offers a short-insert paired-end capability for high-resolution genome sequencing as well as long-insert paired-end reads especially important for RNA sequencing.

Quantitative (q)-PCR

qPCR analysis service request form


The method is based on the conserved 16S rDNA gene present in all bacteria (a comprehensive list of 16S rDNA sequences from gut bacteria have been deposited and categorized in the Ribosomal Database Project II ). By calculating the number of conserved 16S rDNA genes, qPCR can indirectly indicate the number of bacteria present in a given sample. Additionally, appropriate design of qPCR oligonucleotide probes (primers) that can identify the sequence of the 16S gene variable regions allows for the amplification of genes from a specific bacterium of interest whilst excluding all other bacteria, making qPCR a useful tool for quantifying specific bacteria in a complex microbial community.

Clone Library Creation

Clone library creation request form


In order to confirm bacterial identity, PCR-amplified 16S rDNA fragments can be cloned into plasmids and transformed into an appropriate host (usually E. coli). Each transformed E. coli colony will contain only one 16S rDNA PCR-originated fragment from the original sample. A number of colonies are picked randomly and the insert is sequenced. The DNA sequence is then compared to a database (for example RDP II) for identification by DNA homology.
