ZymoBIOMICS Microbial Community Standard II (Log Distribution) 750 µl / 10 Preps

ZymoBIOMICS Microbial Community Standard II (Log Distribution) is a mock microbial community consisting of eight bacterial and two fungal strains. This microbial standard can be used to assess the performance of microbiomics workflows and can also be used as a positive control for routine sequencing. Cells of the ten microbes were mixed in a log-distributed abundance, which allows the user to easily assess the detection limit of their microbiomics workflow. 75 µl of the standard contains about ~1 cells of Staphylococcus aureus, the organism of lowest abundance. If needed, the standard can be spiked into a sample matrix (e.g. soil and blood) to mimic real samples of interest.
