The DuPont™ Lateral Flow System is a simple and inexpensive alternative to traditional culture methods for routinely screening foods for pathogens. This system offers optimized media, requires no capital investment and only minimal training. Low labor and material costs also help make this system a cost-effective screening tool.
At this time, DuPont™ Lateral Flow Systems for Salmonella, Listeria and E. coli O157 (including 0157:H7) are available outside the U.S. only.
Using a unique combination of antibodies and highly engineered colloidal gold conjugate coated on the surface of a membrane, the DuPont™ Lateral Flow System yields clear, reliable results—which are available much faster than conventional, culture-based testing.
After a few simple steps of preparation, the sample wicks up the test strip by capillary action. Within 10 minutes, if the target pathogen is present in the sample, two red lines are formed. If not, only the control line—which lets you know that the test has worked correctly—appears. The test can detect 1 colony forming unit (cfu) in 25 grams of sample.
The DuPont™ Lateral Flow System uses specifically designed media that facilitate the maximum recovery of both sub-lethally injured and healthy cells, while inhibiting closely related competitive flora. Using this optimized media simplifies and shortens enrichment times.
DuPont™ Lateral Flow Systems include test strip and media for Salmonella, Listeria and E. coli O157 (including 0157:H7).
Test strips have a long shelf and can be stored at room temperature, saving valuable refrigerated storage space in your laboratory.
The DuPont™ Lateral Flow Systems have been certified as Performance Tested methods by AOAC Research Institute.
