From Microbiologics we can provide quality control organisms as referenced in ISO 11133 such as Listeria monocytogenes ATCC®13932, Listeria innocua NCTC 11288, and Listeria seeligeri ATCC® 35967 (USDA control strain).
Microbiologics also has available the UV-BioTAG™product range that includes a Listeria monocytogenes strain containing a green fluorescent protein marker. In this way the organism can very easily be identified as a laboratory control strain by the highly visible fluorescence it produces. With UV-BioTAG, you can quickly and reliably establish whether a positive test result can be traced back to a control strain cross-contamination issue, or if it is from another source.
UV-BioTAG, our line of reference strains containing green fluorescent protein (GFP) markers, makes is easy to distinguish standard microorganism strains from laboratory control strains.
