Long-Read Metagenomic Sequencing

Metagenomics sequencing is the way to do genomic analysis of microbial DNA from environmental communities.

It enables the population analysis of unculturable or previously unknown microbes and allows researchers to  comprehensively sample all genes in all organisms present in a given complex sample.

Now Bio Basic Asia Pacific provides long-read metagenomics sequencing service on PacBio SMRT System in a culture-free method.

Long-read metagenomics sequencing help scientists generating new insights into the function and pathway facets of the microbiome, trying to understand and elucidate the relations between microbes and its habitat/host.

This is a powerful way to obtain microbial genomes with the highest accuracy and reliability.

Principle of SMRT sequencing:
Fluorescence from a dye-linked nucleotide is detected during DNA extension.
Different emission from the various dye allow identification of the incorpated base.
