ZymoBIOMICS HMW DNA Standard is a mixture of high molecular weight genomic DNA isolated from pure cultures of seven bacterial and one fungal strains. It has an accurately defined composition, negligible impurities (<0.01%) and contains genomes of a wide range of GC content (15%-85%). This can be used to assess and benchmark the performance of long read/3rd generation sequencing for microbiomics and metagenomics analysis and can also be used as a routine quality control. Theoretical Composition Based on Genomic DNA: Pseudomonas aeruginosa - 14%, Escherichia coli - 14%, Salmonella enterica - 14%, Enterococcus faecalis - 14%, Staphylococcus aureus - 14%, Listeria monocytogenes - 14%, Bacillus subtilis - 14%, Saccharomyces cerevisiae - 2%.
