Red grapefruit effect on gut mouse microbiome Raw sequence reads
Red grapefruit effect on the bacterial population in the gut microbiome was examined by analyzing the prokaryotic 16S ribosomal RNA gene (16S rRNA), which is approximately 1,500-bp long and contains nine variable regions interspersed among conserved regions. These variable regions were subjected to phylogenetic classification, in diverse microbial populations. The following protocol describes a two-step PCR-based method for preparing samples for sequencing the variable V3 and V4 regions of the 16S rRNA gene
