16S Sequencing
Assay Overview
We provide services to sequence various hypervariable regions (V1-V9) of 16S rRNA gene for bacterial taxonomy and phylogeny. Customer can select the hypervariable region/s based on their sample source and study aims.
For commonly studied regions such as: V3 & V4, we use Illumina Nextera recommended primer sets and protocol to amplify the targeted region/s and ligate illumina adapter & barcodes. We also offer in house developed protocol for full length 16S rRNA gene sequencing.

Customers need to provide either original sample (to isolate DNA) or extracted genomic DNA representative of their sample. We recommend 100-500ng (20ng/ul conc.) high complexity DNA to generate high quality 16s sequencing libraries. We use illumina recommended dual indexing to barcode sequencing libraries before pooling. QC pass libraries are precisely quantified using Q PCR before loading onto MiSeqDX illumina platform using 300 PE protocol.
