To determine copy number variation, it is enough to do "shallow" whole genome sequencing, at 0.1-0.2X coverage. To confidently call mutation in heterogenous population of cells, for example in cancer, you might want to go for "deeper" coverage, at 80X or higher. One example of this approach was employed in the academic lab of one of our founders, Dan Knights. As opposed to single gene sequencing such as 16S, SMS is untargeted and covers a much wider proportion of a genome, including whole genomes and non-microbial DNA. In our experience samples with low microbial loads or a high proportion of host genome contamination benefit from using BenchMark™ amplicon sequencing for DeepSeq™ deep shotgun sequencing. This gives you more sensitivity and statistical power than you would get with amplicon sequencing. Researchers have begun to successfully employ shallow shotgun sequencing in their studies. Shallow shotgun metagenome sequencing (SSMS) requires sample sequencing at a shallower depth than is performed in complete shotgun sequencing. Each BoosterShot project includes species-level taxonomic profiling and functional profiling of biological pathways present in your samples. This allowed a much deeper insight into the individual compositional and functional changes in the gut microbiome in response to different dietary patterns than would have been obtained from 16S sequencing alone. Installation. Microbiome Insights now offers shallow shotgun sequencing services. Talk to one of our bioinformaticians about our fully-customizable CorePlus Analysis. to find out how we can help enrich your studies. “Shallow SMS” simply involves sequencing samples at a more shallow depth than is traditionally applied to SMS. We developed algorithms of unparalleled sensitivity to unlock maximum information from sequencing depths of just 2 million reads per sample. Illumina HiSeq 2500 / MiSeq for ultra-deep sequencing with huge data output; PacBio RSII for de novo sequencing with extra-long read lengths; Roche GS FLX++ and GS Junior for excellent amplicon data and Sanger-like reads ; Life Technologies' Ion Proton for … BoosterShot is our CLIA approved and highly-accurate approach to shallow shotgun sequencing that makes full species-level resolution and functional profiling attainable for large scale studies. performances of shallow shotgun sequencing for species and functional profiling with ultradeep sequencing, we obtained ultra-deep WMS sequencing of 2.5 billion se-quences per sample on novel human stool samples from two individuals. The growing use of 16S sequencing has also led to innovations that have enabled a sharp decline in cost, allowing many more researchers to avail of this technique relatively cheaply. Bacterial RNA Sequencing; Eukaryotic Microbial RNA Sequencing; Viral RNA Sequencing; Microbial Isolation & Cultivation. Shotgun metagenomic sequencing allows researchers to comprehensively sample all genes in all organisms present in a given complex sample. Researchers have begun to successfully employ shallow shotgun sequencing in their studies. When deciding which sequencing technique to use, it is essential to consider a number of factors including the research question, study design and cost. By combining many more samples into a single sequencing run and using a modified protocol that uses less reagents for sequencing library preparation, shallow SMS is able to provide compositional and functional sequencing data similar to deep SMS at a cost similar to 16S. Whole genome shotgun sequencing uses a fraction of the DNA that clone-by-clone sequencing needs. Advantages of shallow shotgun sequencing include: Cost … The method enables microbiologists to evaluate bacterial diversity and detect the abundance of microbes in various environments. Shallow shotgun in practice. Examples are human stool and oral samples or fecal samples from model organisims.
