Advanced MultiTag Sequencing™ primer kits and full line of pyrosequencing services are now available from Metabiomics© to the Microbiome research community to increase throughput, productivity, and comparative statistical analysis, differentiating subject populations, samples, and/or characteristics. MultiTag Sequencing™ enables researchers to barcode DNA samples by source which can then be economically sequenced in a single massively parallel pyrosequencing run and then, using bioinformatics and statistical tools, to perform multivariate statistical techniques to perform comparative analysis of sample characteristics, dependent, and independent variables of interest.
