Applied Markets Watch: DuPont BAX System Listeria Assay


DuPont Nutrition & Health this week launched the BAX System Real-Time PCR Assay for Listeria monocytogenes.

The new assay combines shorter, simpler sample preparation and faster real-time processing, without sacrificing accuracy or reliability, DuPont said. The assay is designed to detect L. monocytogenes in a variety of products and has been validated on frankfurters, cooked shrimp, spinach, queso fresco, and environmental surfaces. The assay enables customers to test for L. monocytogenes, Listeria spp., and Salmonella in the same batch, with results for all organisms in a little over an hour.

DuPont said the new assay completes the BAX System portfolio of real-time PCR assays for the common US pathogens. The platform can now test for Salmonella, Escherichia coli O157:H7, non-O157 STEC, Listeria, L. monocytogenes, and Campylobacter, among others.
