Microbiome taxonomic profiling (MTP) is a method to elucidate taxonomic composition of the complex microbial community. The currently available and widely used NGS platforms are Illumina MiSeq (pair-end 250 bp) targeting V3V4 region and Pacific Biosciences (PacBio) targeting full-length. Here, we give statistics on lengths of amplicons.

Various PCR primers that are frequently used to parts of 16S rRNA gene are given here.

The amplification of primers used by ChunLab are:

  • MiSeq primers targeting V3V4 region of Bacteria
341F CCTACGGGNGGCWGCAG
805R GACTACHVGGGTATCTAATCC
  • PacBio primers targeting full-length 16S rRNA of Bacteria
27F AGRGTTYGATYMTGGCTCAG
1492R RGYTACCTTGTTACGACTT

Statistics of amplicon lengths

The lengths were calculated from reference sequences included in EzBioCloud 16S databases (Yoon et al. 2017). The values are without primers.
