Bacterial-specific (300 nM 27F, 5’-AGAGTTTGATCCTGGCTCAG-3’) forward primers coupled to (300 nM 519R, 5’-ATTACCGCGGCTGCTGG-3’) reverse primers were used to amplify Bacterial 16S rRNA. 20 μl SsoAdvanced Universal SYBR® Green Supermix (Bio‐Rad) were run on Applied Biosystems StepOne Plus instrument in duplicate.
| Step | Temperature | Time | Cycles |
|---|---|---|---|
| Initial Denaturation | 95 oC | 3:00 | |
| Denaturation | 95 oC | 0:15 | |
| Annealing | 55 oC | 0:30 | 40 |
| Extension | 72 oC | 0:30 |
Full-length bacterial 16S rRNA gene was cloned into a pCR4-TOPO vector, with Kanomycin-Ampicillin resistance. The total plasmid fragment size is expected to be 5556 bp. An bacterial standard was prepared via. 10-fold serial dilutions, and the copies of 16S was determined by the following: Copy# = (DNA wt. x 6.02E23)/(Fragment Size x 660 x 1E9)
Linear regression was used to determine copy numbers of samples, based on CT of standards.
Reaction specificity was assessed using a melt curve from 55 oC to 95 oC, held at 0.5 oC increment for 1s.
