DNA extraction and purification kit Legionella

Next-generation DNA purification

→ Real-time PCR is a powerful and rapid tool for the specific detection of microorganisms in water.

This methodology, widely used in most countries, is already the subject of multiple ISO standards for the research of microorganisms, like Legionella spp & Legionella pneumophila, in various fields, such as environment or food industry.

Sample preparation (extraction and purification of nucleic acids) is the crucial step of the process.

With the DNA PURE-FLASH kit, our main goal was to eliminate PCR inhibitors while keeping optimal extraction performances.

→ The DNA PURE-FLASH  kit provides a robust and reliable solution for the optimal extraction of DNA from bacteria while ensuring the removal of inhibitors for real-time PCR analysis.

Application fields

The DNA PURE-FLASH kit allows an optimal DNA extraction of the microorganisms present in the water sample. It is used to prepare a sample in order to analyse it by real-time PCR. This methodology can be used on DRINKING WATER (treatment process, water supply units), SANITARY WATER (domestic hot and cold water systems, swimming pools, balneology…) or INDUSTRIAL WATER (cooling system…).

Protocol key points

1. Concentration of bacteria present in the sample by filtration or centrifugation, then, thermic lysis of the cells.

2. DNA retention using the Binding Buffer solution and creation of the polyplex.

3. Retention of the polyplex on a the WCX resin and elimination of the supernatant.

4. Addition of the elution solution and DNA recovery by orbital stirring at 80°C.
