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, our line of reference strains containing green fluorescent protein (GFP) markers, make it easy to distinguish standard microorganism strains from laboratory control strains. 


Optimized for highly visible fluorescence, UV BioTAG strains provide better stability because the GFP marker is integrated into the chromosome rather than the plasmid. 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.
