We have strong expertise in providing the confident and unbiased viral metagenomic sequencing service by employing state-of-the-art high throughput sequencers, sequencing strategies, and bioinformatics pipelines. The Introduction of Viral Metagenomic Sequencing Viruses are the most abundant biological entities in the world which outnumber microbial cells 10:1 in most environments. Viruses constantly inhabit our body, and asymptomatic hosts are no exceptions. This emerging vision raises the need for the exploration of the virome. Viral metagenomics can provide insights into the composition and structure of viral communities. Profiling the taxonomic composition of viral communities is important not only for basic research but also for clinical science and practice. However, viral communities are difficult to be characterized because there is no a single gene that shared by all viral genomes, which limits the application of analogous methods used in bacteria for ribosomal DNA profiling. The low- abundance of free and cellular DNA is another challenge. Metagenomic shotgun sequencing and RNA-seq are two approaches for the characterization of viral communities. Direct sequencing can result in a high background of genetic materials. Therefore, extra procedures are needed to concentrate and purify viral particles (VPs). Multiple viable enrichment methods have been suggested, including filtration, ultracentrifugation, nuclease treatment, multiple displacement amplification (MDA), linker- amplified shotgun library (LASL), and random PCR approach. Advantages of Viral Metagenomic Sequencing •No need for cultivation or antibody laboratory tests •Comprehensive information on community biodiversity, taxonomy, and function

Viral Metagenomic Sequencing Workflow Our highly experienced expert team executes quality management by following every procedure to ensure comprehensive and accurate results. The general workflow for viral metagenomic shotgun sequencing is outlined below. Briefly, the basic steps involved in viral metagenomics include the isolation and purification of viral particles by size filtration or density-based centrifugation, sequence-independent amplification of viral nucleic acid, shotgun sequencing or RNA-seq and matched analyses on diversity, taxonomy, and function through a battery of reliable bioinformatics tools. Service Specification Apart from the qualified viral metagenomic sequencing, we provide assistance, including the experimental design, the determination of the
