From: ddPCR allows 16S rRNA gene amplicon sequencing of very small DNA amounts from low-biomass samples
Taxonomical profiles at the genus level for two human samples (T1, T30) and two mock communities of known composition (Zymo, ZIEL2). For every sample, different initial DNA amounts were used for 1st-step PCRs and, further, different V-regions were targeted
