Microbiologics UV-BioTAG QC microorganisms for quality control testing

Microbiologics is a leading provider of ready-to-use QC microorganisms for quality control testing in the clinical, pharmaceutical, food, water and educational industries. With over 900 strains available in a variety of user-friendly formats, the company offers a large and diverse line of QC microorganisms including qualitative, quantitative, certified reference material and parasite suspensions. Recently, Microbiologics launched the UV-BioTAG product range.

It’s not uncommon for food samples to inadvertently become contaminated with control strains used in the laboratory. This leads to false-positive results, which can have severe financial and regulatory implications. UV-BioTAG, a line of reference strains containing green fluorescent protein (GFP) markers, makes it easy to distinguish standard microorganism strains from laboratory control strains.

Optimised for highly visible fluorescence, the reference strains provide good stability because the GFP marker is integrated into the chromosome rather than the plasmid. Users can quickly establish whether a positive test result can be traced back to a control strain cross-contamination issue or if it is from another source.
