FAQ-3402
What is the difference between LLOQ and LOD?
Limit of detection (LOD) is defined as the lowest concentration at which 95% of positive samples are detected. Since LOD is not necessarily within the linear range of an assay, LOD can be lower than LLOQ.

Microbial DNA qPCR Arrays
Microbial DNA qPCR Arrays are collections of assays to identify and profile microbial species, virulence factor genes or antibiotic resistance genes from a variety of sample types. Species identification assays target bacterial 16S rRNA genes and fungal ribosomal RNA genes, and each array includes controls for host DNA, presence of bacterial DNA and success of the PCR reaction. Microbial qPCR Mastermix is also included in the array kit. The simplicity of the product format and operating procedure allow routine, reliable identification or profiling of microbial species and genes from samples in any research laboratory with access to a real-time PCR instrument. What is the difference between microbial identification and profiling? Identification is determining the microbe’s presence or absence in your sample which requires running a No Template Control during your analysis. Profiling is determining the microbe’s relative expression in two or more experimental conditions for which you will need to run a reference sample and a normalizer (provided by QIAGEN).
Microbial DNA qPCR Assays
Microbial DNA qPCR Assays are a mix of two PCR primers (10 µM each) and one 5′-hydrolysis probe (5 µM) that enables quantitative real-time PCR for 100 reactions. Microbial DNA qPCR Assays are designed using a proprietary and experimentally verified algorithm, providing uniform PCR efficiency and amplification conditions. Each Microbial DNA qPCR Assay undergoes rigorous experimental verification to ensure high PCR efficiency, and this high efficiency is guaranteed when the assays are used with Microbial qPCR Mastermixes and Microbial DNA-Free Water (sold separately).

Microbial DNA qPCR Assay Kits
Microbial DNA qPCR Assay Kits are a complete solution for real-time PCR-based microbial detection. Microbial DNA qPCR Assay Kits contain a Microbial DNA qPCR Assay, which is a mix of two PCR primers (10 µM each) and one 5′-hydrolysis probe (5 µM) that enables quantitative real-time PCR for 20 reactions. The kit also contains everything required for a successful qPCR run, including Microbial DNA Positive Control, Positive PCR Control, Microbial DNA-Free Water, and Microbial qPCR Mastermix.

Microbial DNA-Free Water
Microbial DNA-Free Water is molecular biology grade, nuclease-free water that has been filter-sterilized and UV-treated to eliminate genomic DNA contamination. Quality of the water is tested by PCR using a panel of Microbial DNA qPCR Assays that are sensitive to bacterial and fungal DNA. If none of the PCR assays give a positive signal using Microbial DNA-Free Water as the template in the PCR reaction, then the lot passes. This rigorous process ensures the cleanest possible results for Microbial DNA qPCR Assay or Array experiments.
