Other Materials Required

  1. Stomacher-type bags for sample enrichment. Filtered bags are recommended (Neogen item 6833)
  2. Graduated cylinder, 250 mL (Neogen item 9368)

Media Enrichment Broth Required

  1. ANSR for E. coli Enrichment Broth (Neogen item 9815)
  2. Tryptic Soy Broth, Modified with Acid Digest of Casein (mTSB) (Neogen item 7167A)
  3. 1 L purified water
  4. Phosphate Buffered Saline (Neogen item 8425)


  1. A special lysis reagent is added to the enrichment sample. Target pathogen DNA or RNA is released through the lysis step.
  2. The lysed sample is added to ANSR reagents. A special primer targets specific regions of the pathogen DNA and starts amplification of the DNA, creating millions of copies in minutes.
  3. The amplified segments of the pathogen DNA bind to special molecular beacons which then fluoresce and are detected by the ANSR reader.
  4. Results will be reported in 10 minutes and displayed as positive, negative or invalid.
