Recent advances in single-cell sequencing based technologies allows us to decipher the genetic content and genomic variation of uncultured microorganisms. Traditional 16S/18S/ITS sequencing and metagenomics are limited as they probably miss some rare members and only provide the average results. We provide microbial single-cell genome sequencing to reveal the heterogeneity of microbial populations. Single-virus genome sequencing is also available for answering biological questions concerning microbial communities.

Single-cell sequencing methods has led to a paradigm shift in the field of microbial genomics, away from microbial population analysis and toward comprehensive studies of individual microorganisms. We provide single-cell genome sequencing to decipher the diversity of microorganisms. The workflow of this service generally includes single-cell preparation, cell lysis, single-cell genome amplification, library construction and whole-genome sequencing. We utilize advanced flow-assisted cell sorting (FACS), laser-capture-microdissection, micromanipulation or microfluidic platform to perform single-cell isolation. Which platform to use depends on the sample. The isolated cells are subsequently lysed and each genome is amplified through whole-genome amplification (WGA) methods (multiple-displacement-amplification (MDA) or MALBAC). After WGA, the amplified DNA is used to create libraries for Illumina sequencing.
Besides, we also provide single-virus genome sequencing to investigate the diversity of viruses, as well as viral genome evolution. Microbial single-cell genome sequencing can be used to discover low-abundance microbial members, reveal phylogenetic relationships, infer microbial evolution and explore potential biosynthetic/metabolism processes. It has been applied to a wide range of fields such as scientific research, epidemiology, human health and drug development.
Our bioinformatics analyses generally include read quality control, genome assembly, genome quality control and comparative genomics analysis. Our bioinformatics analysis pipeline is flexible to your needs. Please feel free to contact us.
