qualyfast™ Legionella PCR and DNA Extraction Kits

Detect both Legionella species and Legionella pneumophila from water samples with this rapid, sensitive and specific solution enabled by the qualyfast® Legionella PCR Assay, Free DNA Inactivator, DNA Extraction and Quantification Standards kits.The assay independently detects both Legionella species and L. pneumophilia, includes inhibition control to minimize false-negative results, and offers the option for quantification by using calibrated standards. All consumables required for the workflow are included within the kits, with lyophilized and pre-dosed PCR reagents for ease-of-use.

Minimizes false negatives

  • Free DNA Inactivator removes DNA from non-viable sources commonly found in environmental water samples.
  • DNA Extraction Kits remove environmental contaminants minimizing potential inhibition effects.
  • PCR Assays with simultaneous co-amplification of an Internal Application Control allowing determination of potential inhibition effects.

Increases accuracy

  • Quantification Standards enable PCR detection of Legionella species to be quantified within the 25-25,000 Genomic Unit range.
  • Increases throughput: Multiplexed PCR of the characteristic DNA sequences for species within the Legionella genus and the specific species L. pneumophilia.

Easy-to-use

  • PCR Assay kits contain strips with eight reaction tubes containing lyophilized PCR reagents, DNA free solution and pre-dosed positive-control tubes.
  • Quantification Standards are pre-aliquoted and lyophilized in individual tubes.
  • DNA Extraction Kits contain all the consumables required to extract DNA from environmental water samples.

Optimized workflow

  • Complete end-to-end workflow covering sample preparation using DNA Extraction Kits and Free DNA Inactivator, detection using multiplex Legionella PCR Assay and evaluation of results using Quantification Standards
  • ISO compliant: workflow is compliant with the protocol, experimental design and calculation methods described by ISO/TS 12869:2012
