Performance

Linearity and dynamic range

Microbial DNA qPCR Assays display linear amplification across a dynamic range from 10 to 10⁶ copies of DNA template (see figure, ).

Lower limit of quantification (LLOQ)

The LLOQ is the lowest concentration of template that still falls into the linear range of the standard curve (see figure, ). Across all Microbial DNA qPCR Assays, 93% have an LLOQ of <100 gene copies (see figure, ). 92% of microbial identification assays meet this LLOQ, as do 95% of virulence gene assays and 97% of antibiotic resistance gene assays (see figures, , , and ).

Specificity

Each Microbial DNA qPCR Assay is stringently tested to ensure that it detects only one target species or gene (see figure, ). For assays that do detect more than one target, a list of detected targets and in silico predictions is included on the product sheet.
This specificity is maintained even when samples have high species complexity, such as in stool, sputum, and plaque (see figure, ), and is verifiable by sequencing methods (see figure, ).

Reproducibility

Microbial DNA qPCR Assays are highly reproducible, both in intra- and inter-individual variability tests (see figure, ).

Principle

Microbial DNA qPCR Assays are designed to detect bacterial 16S rRNA gene and fungal ribosomal rRNA gene sequences for species identification, as well as virulence factor genes and antibiotic resistance genes using PCR amplification primers and hydrolysis probe-based detection.

Design your own 96- or 384-well microbial DNA assay plate from our selection of predesigned Microbial DNA qPCR Assays. Choose a fully flexible plate layout or select from several convenient predefined layouts. Use our easy-to-use online plate configurator to position the predesigned Microbial DNA qPCR Assays of interest into your plate. The arrays will be delivered ready-to-use, with one single assay per well, sufficient for a 20 µl reaction volume. The Master Mix is provided with the arrays.

The table below displays the many different plate layout combinations available for each plate format. Select the plate layout that suits your needs; for example, configure a 96-well plate with 48 assays to be used with 2 samples, or a 96-well plate with 12 assays to be tested with 8 samples.

We highly recommend that you include controls on each Custom Microbial DNA qPCR Array. Controls are available for testing for the presence of fungal DNA, bacterial DNA and host genomic DNA and for assessing the success of the PCR reaction, so you can be confident in the results.

Procedure

The Microbial DNA qPCR Array procedure is simple and can be carried out in any laboratory with a real-time PCR instrument. DNA is isolated using the QIAamp kit that is suited for the sample type, and then mixed with the appropriate Microbial qPCR Mastermix. The mixture is aliquotted across the array plate, and real-time PCR is performed to obtain the raw C_T values for each assay. The complimentary data analysis software is then used to profile genes or species in the sample.

Applications

Custom Microbial DNA qPCR Arrays are highly suited for the rapid and accurate profiling of a custom panel of microbial species, virulence factor genes, or antibiotic resistance genes. For example, a microbial species identification panel assembled by our experts was used to explore the underlying causes of bacterial vaginosis (see figures, and ), while a panel for antibiotic resistance genes identified these genes in samples from the gut or from sewage (see figures, and ).

See figures

The Vaginal Flora Microbial DNA qPCR Array provides accurate profiling for cervical swab samples.

Vaginal samples positive for Gardnerella vaginalis also show changes in commensal and bacterial vaginosis-related microbes compared to healthy samples.

The Microbial DNA qPCR Array screens gut microbiota for the presence of antibiotic resistance genes.

The Antibiotic Resistance Genes Microbial qPCR Array identified antibiotic resistance genes in sewage samples.

Supporting data and figures

Linearity and sensitivity of Microbial DNA qPCR Arrays.

Linearity and sensitivity for each Microbial DNA qPCR Array was determined using synthetic templates over a 6 log serial dilution ranging from 1 copy to 1 million copies. The following are representative results for all the qPCR assays. [A] shows the real-time amplification curves of the KPC antibiotic resistance gene qPCR assay. In [B], a standard curve was prepared that shows that the primer efficiency equals 103% (calculated from slope = –3.3236) and the correlation coefficient is 0.9983, indicating optimum performance for the KPC qPCR assay. All Microbial DNA qPCR Assays have primer efficiencies between 80–120% and correlation coefficients (R)>0.995.
