The DuPont™ Lateral Flow System test is an immunoassay with built-in controls. It employs a unique combination of anti-E.coli O157 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 E. coli O157, including O157:H7, is present in the sample, two red lines are formed.
Using the DuPont™ Lateral Flow System media for E. coli O157 reduces enrichment time to just 8 hours for beef samples (can be extended to 18 hours to fit with your lab's work flow). The media powder is mixed directly with sterile water for immediate use. You can also use the test with standard 20-hour enrichment broths for beef and fruit juice.After enrichment, you can choose to heat-treat the samples or test them immediately. Simply drop the test strip into an aliquot of sample broth, and read the results 10 minutes later. One control line is built into the lateral flow strip so you know the test has worked correctly. Two lines indicate a positive result. Test strips are stored at room temperature.
The DuPont™ Lateral Flow System E. coli O157 test is designed to detect E. coli O157, including O157:H7, in raw beef (boneless and ground) and processed foods, including fruit juices. The test can reliably detect 1 cfu in 25 grams of sample.
