    About 16S rRNA Bacterial flora analysis

    Service Overview

    Next-generation sequencers are used to sequence regions of high genetic diversity in bacterial 16S rRNA genes to identify and estimate the proportion of bacterial flora. Negative controls are used to identify background bacteria of environmental origin and a report containing the correlation between samples and a negative control, is included. In addition, contamination by environmentally-derived bacteria brought in from reagents is minimized, so even samples with low amounts of bacteria can be analyzed.


    ・Analysis from a single sample is possible at our laboratory in Japan.
    ・Analysis of low-biomass samples with small amounts of bacteria is possible using a special method developed by us.
    ・Bacteria are identified using the world standard Silva database and the germline databases.
    ・Analysis down to the species level is possible.
    ・Well-versed with various clinical specimens including vaginal, uterine tissue, breast milk, saliva, and oral cavity tissues.
    ・May be able to perform Test on non-fresh samples (FFPE sections, Gram stain slides, etc.)
    ・Statistical analysis for papers and conferences is also available (consultation required, additional cost)
