More than 99% of natural microorganisms cannot be isolated and cultured through the traditional isolation process. Samples separated from the environment can be used to explore microbial diversity. The 16S rDNA, 18S rDNA, and internal transcribed spacers (ITS) have been widely used for microbial taxonomy and molecular systematics by a combination of PCR and sequencing methods. We provide full-length 16S/18S/ITS sequencing for microbial diversity analysis of clinical or environmental samples. This method is able to discriminate microbial strains between closely related organisms.

The 16S/18S/ITS amplicon sequencing is a precise, sensitive, and cost-efficient tool for microbial diversity analysis and is utilized in thousands of published studies each year. However, this tool is typically restricted to sequence nucleotides between 100-500 bp, which may limit researchers by obtaining only the fragments of preferred taxonomic barcodes. PacBio and Oxford Nanopore have developed novel sequencing platforms that can generate long reads of tens of thousands of nucleotides, which easily span the full length of 16S/18S/ITS. We provide comprehensive full-length 16S/18S/ITS sequencing service based on PacBio SMRT sequencing or Oxford nanopore sequencing platforms for microbial diversity analysis, species classification, and functional profiling.
As a tool for metagenomics, full-length 16S/18S/ITS sequencing based on long-read sequencing can achieve species and even strain-level taxonomic resolution, which can be difficult to achieve using the next-generation sequencing (NGS). Full-length 16S/18S/ITS sequencing can provide more information on microbial diversity, phylogeny, and biological function. Its value has been assured in applications such as characterizing histocompatibility and tracking diversification of HIV env gene.
