Stan Langevin was interested in seeing if the RLOv (phage) and/or the prophage portal genes were detectable in water samples from Lisa’s Ab Endo project.
Ran qPCR on the following samples that Lisa selected:
DNA from water filters collected in 2010. DNA isolated 20120111:
- CP 0M A
- CP 0M B
- MA 0M A
- MA 0M B
- PSN 0M A
- PSN 0M B
- RM A
- RM B
DNA from water filters collected in 2011. DNA isolated 20140822:
- AM Drain 2B
- PCI SRI PC 1B

RLOv_DNA_helicase standard curve from 20151224.
All samples were run in duplicate. Plate layout, cycling params, etc. can be seen in the qPCR Report below.

- RLOv DNA helicase amplified in all samples EXCEPT the two samples from 2011. These two samples were negative for the RLO (see Ab Endo sheet “water 2011″).
- XC prophage amplfied inconsistently (i.e. replicates did not match/amplify) in only three samples. Additionally, the melt curve of one of those samples differs from the other two. Based on the inconsistencies in technical reps, I should probably repeat this, but technical reps across all of the RLOv DNA helicase samples are very tight, suggesting that my technique was fine (it would be odd if my technique faltered only on ALL of the XC prophage samples)…
