Earth microbiome project primers
Web13 ott 2024 · V9 universal primers have been adopted as a standard tool of the global cataloguing effort the Earth Microbiome Project (Gilbert et al. 2014). On the other hand, the V4 region is longer and, thus, more phylogenetically informative, and is better represented in the SILVA and PR 2 databases (Geisen et al. 2024). WebHMR16S The HMP performed 16S short variable region sequencing on over 10,000 samples collected from 15-18 body sites from 300 healthy human subjects. For more detail, see Microbiome Analyses. A subset of these samples were described in a series of 2012 publications in Nature and PLoS.
