Improved workflow

Unlike other Pyrosequencing instruments, the PyroMark Q48 automates the Pyrosequencing workflow by using discs and magnetic beads for the Pyrosequencing protocol. The instrument touch screen guides users through each step thereby reducing errors.

Advanced technology, software and chemistry for long and reliable sequence runs

The PyroMark “Advanced” chemistry and algorithms have lower backgrounds than the older “Gold” chemistry such as used by the PyroMark Q96 ID. This results in increased read length and reliability. Depending on the sequence to be analyzed, accurate read lengths of 140 or more bases can be obtained in just a single reaction.

Compatibility of assays among different PyroMark platforms

QIAGEN provides best practice recommendations on how to transfer assays to the PyroMark Q48 Autoprep Instrument. With some optimization, previously designed Pyrosequencing assays using other PyroMark instruments can be made compatible with the new PyroMark Q48 Autoprep Instrument. When optimized, the same mutation frequencies and methylation quantification results are obtained when an assay is run on the various PyroMark platforms (see Compatibility among PyroMark platforms for mutation analysis and  Compatibility among PyroMark platforms for methylation analysis). The cross-platform compatibility is also independent of the distance of the analyzed site away from the sequencing primer. This is particularly important when analyzing multiple sequence variations in a single run, typical for complex mutation assays or methylation analysis of consecutive CpG sites.

New disc design enables magnetic template preparation without cross contamination

PyroMark Q48 Discs are specially designed to automate template preparation and Pyrosequencing in the same instrument without manual user interaction. All buffers used for template preparation are efficiently removed from the sample and the disc during the run without the risk of any cross-contamination from well-to-well of one run or from disc-to-disc between subsequent runs (see  Excluding well-to-well and disc-to-disc cross-contamination).

Increased throughput for more SNP and mutation assays per run

Multiple Primer Dispension (MPD) is a strategy to increase the capacity of automated sequencing primer dispension in cases where more assays are needed than cartridge reservoirs are available. The PyroMark Q48 Autoprep Primer Cartridge has 3 reservoirs, but if more assays are needed per disc, the primers can be mixed and filled into the same reservoir of the primer cartridge. After template preparation, primer mixes are dispensed into the wells automatically. Since only one PCR template is present in each well, only the corresponding sequencing primer will bind to the template. All other primers will stay in solution and therefore will not bind (see  The principle of multiple primer dispensation). Primers in each MPD mix should be designed and checked to avoid formation of primer–dimers or binding to another PCR template.

PyroMark PCR and RT-PCR kits

The PyroMark PCR and PyroMark RT-PCR Kits are provided in a master mix format and are specifically optimized for Pyrosequencing analysis. The RT-PCR mix contains Omniscript and Sensiscript reverse transcriptases, a combination that provides highly efficient and sensitive reverse transcription from 1 pg to 2 μg of starting RNA. Both the PyroMark PCR and PyroMark RT-PCR Kits use HotStarTaq DNA polymerase. This enzyme is activated by a 15 minute, 95°C incubation, a step that often increases the yield of the specific PCR product.

The PyroMark PCR and PyroMark RT-PCR Kits also use Q-Solution, an innovative additive that facilitates and improves PCR amplification of difficult templates by modifying the melting behavior of DNA. CoralLoad Concentrate is also included, and its use has been linked to an improvement in yields. CoralLoad PCR Buffer provides the same high PCR specificity and minimal reaction optimization as the conventional QIAGEN PCR Buffer. Additionally, it contains two gel marker dyes for improved pipetting visibility and enhances convenience by enabling direct loading of PCR products onto a gel (see CoralLoad Concentrate for convenient gel loading of DNA).

PyroMark CpG assays

The PyroMark CpG assays use a design algorithm specific for CpG results that have a high success rate. The assay database includes over 84,000 assays for gene-specific human, mouse and rat CpG sites. We also offer predesigned assays for validating results from methylation arrays, such as the Infinium HumanMethylation450k and MethylationEPIC BeadChip arrays, through the provision of CpG loci identification numbers (CG#). (see  High Pyrosequencing success rate of predesigned PyroMark CpG assays).

Depending on the platform used, the following reagent kits are required for pyrosequencing:

FAQ ID -2822
How do I reduce background peaks in the pyrosequencing pyrogram?
There are several reasons for a high assay background; the template can form secondary structures that are extended or the primers itself form dimmers that serve as template. Perform accurate sequencing controls (e.g., PCR or sequencing primer only) as recommended in the PyroMark User Manual to observe this kind of background. In addition, an unspecific priming of primer to template or unspecific annealing of sequencing primer to template might also be a background cause. Please check your complete primer design and, if needed, perform a redesign. Try to lower the primer concentration as possible to avoid excess of primer.
FAQ ID -2877
What is the sample throughput of pyrosequencing systems?

PyroMark instruments offer a range of throughput scales. The PyroMark Q24 can process 1–24 samples in parallel, the PyroMark Q48 Autoprep, 1–48; the PyroMark Q96 ID, 1–96; and the PyroMark Q96 MD, 1–96; or the automation option enables automated processing of ten 96-well plates. The sample processing speed depends on the number of nucleotide dispensations necessary for the programmed analysis. Twenty dispensations take approximately 24 minutes on all instruments; thus, 96 samples are typically processed in 10–100 minutes.

Primer sequences for PyroMark CpG Assays are not provided; they are proprietary.
FAQ ID -2823
Which purity grade is recommended for pyrosequencing primers?
Only the biotinylated primer needs to be HPLC purified, whereas the other primers require standard desalting only.
FAQ ID -2832
Will dUTP in a PCR reaction affect pyrosequencing?
In general, dUTP/UNG treatment should work for pyrosequencing to reduce contamination risk with PCR amplicons from previous PCRs.
FAQ ID -2843
What is the purpose of the unmethylated and unconverted control DNA of the EpiTect PCR Control DNA Set?

The unmethylated and unconverted human control DNA of the EpiTect PCR Control DNA Set allows to check that primers designed for the specific detection of unmethylated and converted DNA (U-converted DNA), and for methylated, converted DNA (M-converted DNA) does not bind to untreated genomic DNA.*

In case bisulfite conversion was not complete, leaving certain unmethylated C residues unconverted, false positives would result if the primer specific for M-converted DNA binds to untreated gDNA.

This control DNA can also be used to check conversion efficiency during bisulfite treatment.

 

*Summary of principle: Methylation of DNA occurs on cytosine residues, especially on CpG dinucleotides enriched in small regions of DNA. Incubation of target DNA with sodium bisulfite, using, for example, EpiTect Bisulfite Kits, results in conversion of unmethylated cytosine residues into uracil, leaving methylated cytosines unchanged.

 

FAQ ID -2007
What kind of reading length can I expect when using pyrosequencing technology for sequence analysis?

Typical reading length using pyrosequencing technology is 40−60 bases. However, as with any sequencing technology, the maximum read length will depend on template secondary structure, base content, quality of PCR-product, and other parameters.

Depending on the sequence to be analyzed, highly accurate read lengths of 140 bases or more can be obtained in just a single reaction with the Q48 PyroMark Autoprep.

 

 

FAQ ID -2216
What is the recommended amplicon size for CpG assays?
The amplicon length should be short (<200 bp). This is critical especially for DNA from FFPE tissue that is often degraded by the fixation so that short fragments are easier to amplify. Moreover, the DNA suffers from harsh bisulfite treatment and might receive further double strand breaks. Therefore, the amplicon size should be kept as short as possible.
FAQ ID -2825
Can PyroMark Gold reagents be vortexed?
Reconstiuted enzyme and substrate of PyroMark Gold Reagents, should not be vortexed since this could lead to conformational changes which affect the activity.
FAQ ID -2844
How do I set up a PyroMark CpG Assay?
All relevant information regarding PyroMark CpG Assay setup can be found on the GeneGlobe website. For the Q24 and Q96, the "Sequence to Analyze" and dispensation order should not be copied manually to create a new assay. Instead, the assay file should be downloaded from the web and opened in the PyroMark CpG softwarePyroMark Q96  ID v2.5 (or higher) software, and PyroMark Q24 Software to keep important software settings.

When using the PyroMark CpG assays with the PyroMark Q48, use the "Sequence to Analyze" provided in the "product specification" section to create an assay setup file in the PyroMark Q48 software. This is done by selecting New CpG assay and pasting in the Sequence to Analyze (not the "sequence after bisulfite treatment") into the Sequence Before Bisulfite Treatment field and pressing Create Dispensation order.
