Overview
The RapidFinder™ Direct Lysis Protocol is a simple, rapid method for preparation of
nucleic acid for PCR from enriched cultures of food and environmental samples. The
protocol is intended for use with cultures enriched for E. coli O157:H7, Salmonella spp.,
Listeria monocytogenes, or Listeria spp.
Enriched cultures are treated with Proteinase K in a specially formulated Lysis Buffer
at 55°C for 30 minutes, followed by heat inactivation of the Proteinase K at 95°C. The
procedure can be completed in about 45 minutes with minimal hands‐on time. The ly‐
sate is ready for use in downstream PCR using one of the following detection kits as
appropriate for the pathogen of interest.
