DuPont™ Lateral Flow System


The DuPont™ Lateral Flow System test is an immunoassay with built-in controls.It employs a unique combination of anti-Listeria antibodies and a highly engineered colloidal gold conjugate coated on the surface of a membrane. The sample wicks up the test strip by capillary action. If Listeria is present in the sample, two red lines are formed.

The DuPont™ Lateral Flow System Listeria media provides a single-stage enrichment, with no transfers required. Simply mix the powdered media base with sterile water and add the supplement before use for results in 40 hours.


The DuPont™ Lateral Flow System Listeria test is designed to detect Listeria on environmental surfaces and in a variety of ready-to-eat foods (such as deli meats, chicken nuggets, pepperoni, hot dogs, chicken salad and potato salad), dairy products (such as ice cream, soft cheese and milk), and fish products (such as cooked shrimp and smoked fish). The test can reliabably detect 1 cfu in 25 grams of sample, and has been certified by AOAC Research Institute as a Performance Tested method.
