WARNING! Read the Safety Data Sheets (SDSs) and follow the handling in‐
structions. Wear appropriate protective eyewear, clothing, and gloves. Safety
Data Sheets (SDSs) are available from www.lifetechnologies.com/support.
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.

Prepare DNA by direct lysis of enriched cultures
Before you begin: culture food or environmental samples for the pathogen of interest
as described in Appendix A, “Sample enrichment”.
1. Prepare sufficient Lysis Solution Mix for the number of reactions required, plus
10% overage.
Component Volume per reaction
Lysis Buffer, FS 63 µL
Proteinase K, FS 10 µL
Nuclease-free Water 127 µL
2. Distribute Lysis Solution Mix and enriched cultures to the appropriate wells in a
standard 96‐well PCR plate.
Component Volume per well
Enriched culture 5 µL
Lysis Solution Mix 200 µL
3. Seal the plate with an aluminum plate seal.
Ensure that the wells are sealed properly, to avoid evaporation and cross‐con‐
tamination.

4. Invert the plate at least 5 times to mix the enriched culture with Lysis Solution
Mix.
5. Load the plate in a thermal cycler and run the following program:
Temperature Time
55°C 30 min
95°C 10 min
4°C ∞[1]
[1] Hold at 4°C until the plate is removed for use in PCR or for storage.
The lysate is ready for PCR using the appropriate MicroSEQ® detection kit for the
pathogen of interest.
Use 30 µL of lysate per PCR assay.
Pipet the lysate directly from the plate by puncturing the aluminum seal with the
pipette tip.
Note: If you use a pierceable aluminum foil seal other than the one recommen‐
ded, be sure to check for clogged tips when pipetting samples.
STOPPING POINT Store the sealed plate at 4°C for up to 72 hours, or store long‐term at
–20°C.
If the seal has been punctured, place another seal on top of the original seal before
storage. Do not remove the original seal from the plate, to avoid cross‐contamination.
