Library Preparation

Whole DNA is prepared for sequencing using the Illumina Nextera XT DNA library prep kit. Samples are barcoded and mixed together for sequencing. The pooled samples are sequenced using Illumina technologies for paired end reads.

The number of samples multiplexed depends on the sample type (i.e. samples that contain more host DNA or complex communities requiring more sequencing depth need consideration). For fecal samples, we recommend at least 1 Gigabase per sample to achieve shallow sequencing, which provides basic taxonomic functional profiling.

Shotgun Sequencing

Paired reads are concatenated and then processed to remove adaptors, barcodes, and low-quality reads, as well as contaminant sequences (typically, host DNA). Sequences are then compared to phylogenetic and functional databases to obtain taxonomic and functional profiles.

We provide sequencing on the Illumina MiSeq platform.

Custom reporting can be done after consultation with our bioinformaticians to understand your particular requirements.
