This procedure is automated on the AutoPure LS instrument."

    Service provided by the Genomic Samples Services Sub-Facility.

  • DNA sequencing (standard) service

    "The DNA Sequencing Core Facility's standard sequencing service consists of preparing and cleaning sequencing reactions, checking the quality of the results, and posting the chromatogram and text files for each sample on-line. For larger PCR sequencing projects, the Core offers an additional PCR purification service preceding the sequencing reaction preparation. Customers may also submit a full plate of pre-run sequencing reactions that have been purified and are ready to be placed directly into the sequencer upon arrival to the Core. Also, a full high-throughput PCR sequencing project can be conducted in the Core starting with genomic DNA and primers through to sequence results. If interested in using the Core's full PCR sequencing service, please contact sequencing@iddrc.org for more information."

    Service provided by DNA Sequencing Core Facility subsection.

  • Gene expression service

    "Basic service consists of providing the Core with total RNA. The Core will first run the samples on a bioanalyzer to assess sample quality. If the samples pass this assessment, the Core processes the samples through to running the arrays on the scanner. Customers are provided with all the array files associated with their runs. Hybridization-only services are also available for labs that perform their own amplification, reverse transcription and labeling reactions. Please contact the Core at microarray@iddrc.org for any specific processing questions."

  • Genomic mapping facility standard service

    "The Genomic Mapping Facility standard service consists of running reactions using our in-house markers from the Applied Biosystems Human Linkage Mapping Set MD10 (markers are located at ~10 cM distance). Once the reactions are completed and data has been generated, the alleles are called and a table of allele data along with the chromatograms is sent to the end user. For custom microsatellite marker projects, users can submit pre-run reactions to the Core and receive the raw data file results. For help with analysis or designing custom projects, please contact the Core at mapping@iddrc.org."

  • Master 96-well plate sample preparation

    "The Core will also plate samples for labs that require this format for downstream applications. Our master 96-well plate preparation involves manual transfer of samples from single tubes/cryovials to a 96-well plate format for applications such as PCR, genotyping, or sequencing reactions. The Master plate is intended as a 'stock solution' preparation that may be used for a number of downstream applications, not just one assay. Master plates increase efficiency for high-volume, high-throughput sample use. Replicate plate preparation is performed on a master plate and intended for use in a single or limited number of assays. The Tecan Genesis Robotic Workstation 150 is used to transfer volume from a master plate to a replicate plate for immediate use."

  • Next-generation sequencing service

    "The Next-Gen Sequencing Facility is currently preparing SOLiD instrument runs for full slides on fragment libraries. Fragment libraries include whole genome resequencing, targeted resequencing (using Agilent SureSelect technology), RNA-seq, ChIP-seq, and small RNA libraries. Customers may create their own libraries after project consultation with the Core and submit them for quantitation and processing. Library preparation is also available in the Core for whole genome, whole transcriptome, and small RNA fragment libraries.

    A full slide instrument run consists of all post-library construction processing through to providing sequence data as follows. The Core performs a quantitative PCR (qPCR) assay on every library to determine its concentration. Using the information from the qPCR, the Core performs a series of emulsion PCRs (ePCR) to amplify template onto beads with individual fragments from the library (or pool of bar-coded libraries). At this stage a spike-in control library is added for processing validation once the run is complete. The completed ePCR then undergoes a breaking and enrichment procedure to release the templated beads from the oil mixture and to enrich for the templated beads that will be deposited onto slides to run in the SOLiD instrument. Before a full run is conducted in the SOLiD, a quality control run is performed to ensure that the ePCR and breaking worked properly. Once the beads pass the QC run, a full slide run is performed on the instrument. Upon completion, each customer is provided with the color space sequence data and run quality data. The Core will keep a record of this data as well as the raw intensity files in permanent electronic records, however the intensity files are not necessary for downstream analysis. All image data is discarded once the sequence run alignment is confirmed by analyzing our spike-in control library data.

    As of July 2009, the MGCF has teamed up with Geospiza to offer SOLiD sequencing bioinformatics support through their GeneSifter on-line application. Use of this software is included in the cost of an instrument run for up to three months after data is posted. This software allows users to perform alignments to their reference species as well as perform downstream data analysis. Currently, analysis pipelines are available for RNA-seq, Digital Gene Expression, genomic resequencing and small RNA SOLiD sequencing runs, but many more analysis pipelines are under construction and will be available soon. For more information about using the GeneSifter application through the Next-Gen Sequencing Facility, please email nextgen@iddrc.org."

  • Picogreen DNA quantitation

    "Picogreen DNA quantitation is strongly recommended for accurate DNA concentrations. Picogreen is highly selective for double-stranded DNA unlike absorbance at 260nm which may reflect the presence of RNA and other contaminants. Sample aliquots and dilutions are suggested after performing the Picogreen assay and prior to long-term storage. Sample aliquots minimize freeze-thaw cycles and may help prevent sample loss by limiting contamination and allowing for storage in multiple locations. Dilutions will minimize workload for downstream applications with uniform sample requirements. Also, transfer to cryovials is recommended to minimize storage requirements and maximize available space."

  • RNA purification service

    "RNA purification in the MGCF is performed using the PAXgene Blood RNA system. The PAXgene tubes contain an RNA stabilizer that allows the blood to be stored without RNA degradation. Customers provide the Core with their collected PAXgene blood RNA Tube and the Core performs the extractions on the QIAcube instrument using the PAXgene Blood RNA Kit, which utilizes a silica-membrane-based spin-column technology. Whole genome amplification is performed using Qiagen REPLI-g Kits. REPLI-g relies on multiple displacement amplification technology and phi29 DNA polymerase to create highly uniform DNA amplification across the entire genome with minimal sequence bias."

  • SNP and qPCR 7900HT instrument access

    "In 2004, the laboratory of Louis Kunkel in the Genomics Program at Children's Hospital Boston purchased an Applied Biosystems 7900HT System for real-time quantitative PCR (qPCR) and single-nucleotide polymorphism (SNP) detection. This instrument is now available for use by other labs interested in performing these tests. Users may prepare their TaqMan or SYBR Green reactions in their own labs and then load them on the 7900HT instrument in either 96-well or 384-well plate format."

  • SNP genotyping service

    "Customers provide the Core with DNA and samples are completely processed through scanning in our array readers. For assistance in project planning or designing custom array projects, please contact microarray@iddrc.org."

    Service provided by the Microarray Core Sub-Facility.
