Oral Microbiome and Pancreatic Cancer

extraction of genomic DNA from oral samples using the Mobio DNA Isolation Kit. 16S rRNA amplicons covering variable regions V3 to V4 will be generated using primers (347F-5'GGAGGCAGCAGTRRGGAAT'-3' and 803R 5'-CTACCRGGGTATCTAATCC-3')66 incorporating adapters and a sample barcode sequence at PI's lab. Amplicons will be sequenced with the Roche 454 FLX Titanium sequencing system at the NYU genome technology center, following the manufacturer's specifications.
