16s Ribosomal Sequencing
What is 16s rRNA Sequencing?
16s rRNA sequencing has become one of the leading methods for phylogenetic studies. The popularization of 16s sequencing methods has been due in large part to the wide availability of PCR and Next-generation sequencing facilities, such as MRDNA. But what is 16s rRNA sequencing? And why should you choose 16s sequencing methods over other DNA sequencing methods?
16s rRNA sequencing refers to sequencing the 16s rRNA gene that codes for the small subunit (SSU) of the ribosome found in prokaryotes such as Bacteria and Archaea. There are several factors that make the 16s rRNA gene the perfect target to complete your taxonomy or phylogeny studies.
Often times, researchers will have some confusion regarding the differences between 16s metagenomic sequencing methods and shotgun metagenomic sequencing methods. In short, shotgun metagenome sequencing is aptly named due to the fact that the goal of this DNA sequencing method is to sequence all genes from all organisms in a given sample. Whereas in the case of 16s metagenome sequencing, the goal is to sequence the 16s rRNA gene specifically.
The initial objective of the many studies within these fields among others is often the same; identify which microbes are present, or more importantly, which are absent. The 16s rRNA gene is an excellent sequencing target in order to complete such studies. There are nine hypervariable regions found in the 16s rRNA gene, and each of these regions is flanked by a highly conserved region. Our in-house 16s rRNA sequencing primer pairs are specifically designed to target these flanking conserved regions thereby allowing us at MR DNA to perform PCR amplification and DNA sequencing of your submitted microbial samples. Of the nine hypervariable regions found in the 16s rRNA gene, some regions may be better suited to complete certain phylogenetic studies over others. Feel free to consult our experts at MR DNA is order to determine which 16s rRNA primer pair is best suited to meet your sequencing needs.
