PureMolecular, LLC is a University of South Florida spin-off company formed in mid-2014 that provides services and technology for microbiological testing and seafood quality control. We have developed a genetic amplification assay that enables identification of the majority of fish labeled as “grouper” from less valuable substitutes. PureMolecular, LLC offers standard U.S. FDA recommended seafood authentication services as well as field instrumentation and reagent kits for “point of use” seafood verification. Our company offers a range of other plug-and-play assays targeting noxious microbes found in marine waters as well as custom assay development.
