![]() Users can also proceed directly to the analysis using the recommended defaults. Highlighting may be included in the print reports as well.įigure 9: GeneMarker allows for easy customization of analysis settings. These probes will also be displayed as triangles in the ratio plot. JPEG formats.įigure 8: Highlighting helps draw attention to probes of particular interest. Reports may be printed directly, or electronically saved in. If the Quality Control Fragments do not pass, a failed message will be shown in red font on the final report. They can be customized to display the entire sample, a particular peak, or clusters of peaksįigure 7: When the Automated Quality Control Settings are used, the final report will denote whether the Quality Control Fragments passed or failed. This setting can be turned on/off under View Preferences.ĭetailed Reports Ensure Results are Communicated Clearly and Effectivelyįigure 6: Reports include an informative header, electropherogram, ratio plot, validation box, and report table. Saturated and Saturated/Repaired peaks are not recommended for any quantitative calculations and will result in a pop-up warning message.Īdditional Quality Warnings for Analysts moving to Post-genotyping Applicationsįigure 5: If there are flagged alleles present in one or more of the samples, the program will warn the user when attempting to access a Post-genotyping Application before the flags are resolved. The detected peak will be given the Quality Reason, SD, and a red underscore at the corresponding location on the electropherogram. These settings help make quality control easier and more rigorous.Īutomated Detection and Repair of Saturated Peaksįigure 4: Saturation Detection (SD) will detect saturated peaks. The program will alert the user if one or more of the Quality Control Settings are turned off (as shown in Figure 3).įigure 3: The program automatically detects important quality control fragments within each sample, and alerts the user if the behavior of any fragment is outside of the norms recommended by MRC Holland. Both methods improve the linearity of the data, allowing more accurate and consistent results.Īutomated Quality Control Increases Rigor and Efficiencyįigure 2: The Quality Control Settings are automatically turned on when the MLPA template is selected. Control Probe Normalization uses the internal control probes to normalize peak heights (recommended by MRC Holland for most chemistries) whereas Population Normalization uses all probes in a sample to normalize peak heights (recommended for chemistries that do not have internal control probes throughout the main marker for the kit. MLPA Normalization Increases the Accuracy and Consistency of Analysisįigure 1: GeneMarker software gives users two methods of data normalization. (In this example there is one heterozygous deletion, and seven homozygous duplications.)įigures 1 – 11 provide details on the MLPA analysis workflow in GeneMarker software. ![]() The resulting peak ratios are plotted in the ratio plot below, and are reported for each sample in the Report Table to the right. >The trace comparison (top, middle) shows a direct comparison between the selected sample and the reference. ![]() GeneMarker software’s MLPA analysis screen comparing test samples (blue trace) to normal controls (red trace).

Click here information on analysis of MLPA data from Next Generation platforms such as Illumina or Ion Torrent and Download the application note NextGENe Batch CNV - MLPA Replacement ( PDF) Analysts can access MLPA panels through GeneMarker software's panel editor, our website, or GeneMarker software's MLPA application has been validated by research hospitals worldwide, is included in EuroGentest validation report, and is an excellent alternative to GeneMapper® and Coffalyser.Net Software. GeneMarker software is compatible with outputs from all major sequencing systems, including ABI®PRISM, Applied Biosystems® SeqStudio™, and Promega Spectrum Compact genetic analyzers, as well as custom primers or commercially available chemistries. MLPA analysis with GeneMarker software is both rapid and accurate, allowing complete MLPA or MS-MLPA analysis of 96 samples in just minutes. The MLPA analysis application is linked directly to the program, allowing the user to process raw data, normalize samples, and perform MLPA analysis all in one program, eliminating unnecessary data transfers. GeneMarker software provides an entire module dedicated to MLPA analysis in-house, no internet needed. Kits are commercially available through MRC Holland. Multiplex Ligation-dependent Probe Amplification (MLPA) is a rapid, high-throughput technique for detecting copy number changes, with both general and clinical research applications.
