Assurance GDS® is an assay that uses the PickPen® Immunomagnetic Separation (IMS) technology for pathogen enrichment prior to PCR detection. Magnetic particles coated with antibodies specific to the target pathogen capture and bind these.
By separating the pathogens from the inhibitory background and concentrating them, the sensitivity of the assay is significantly improved. After washing, the magnetic particles are released and transferred to the amplification tubes for PCR analysis, with each tube containing all the reagents in a ready-to-use pellet.
The benefits of PickPen® IMS combined with the dual specificity of the Assurance® GDS DNA primers and probes, and the rotary format thermocycler, results in a pathogen detection system that offers unparalleled sensitivity and accuracy. Assurance® GDS is currently used in a variety of industrial and commercial food testing labs for the detection of E. coli O157:H7, Salmonella, Salmonella HET, Shiga Toxin Genes, Listeria spp, Listeria monocytogenes, Shiga Toxigenic E. coli (STEC), and Cronobacter.
MilliporeSigma, the US life science business of Merck KGaA in Darmstadt, Germany, is here to partner with food safety teams enabling you to improve lab testing efficiencies with reliable products and services that meet ever-changing regulations.
It is through our collaborations that we can advance the safety and analysis of foods and beverages using trusted brands like Millipore® with microbiology solutions for hygiene, environmental monitoring & pathogen detection; Supelco® analytical solutions for the analysis of food contamination and authenticity; Milli-Q® lab water solutions; and Sigma Aldrich lab and production materials, including chemicals, inorganics and solvents throughout the supply chain, manufacturing and distribution.
In this podcast, FoodBev is joined by MilliporeSigma’s senior scientist for new technology evaluation, Markus Jucker. Jucker discusses the importance of employing pathogen detection techniques in ensuring food safety.
