Gene expression variability across the genome has significant impact on understanding the progress and prognosis of cancer. The Cancer Functional Genomics Core at the Stephenson Cancer Center offers cutting-edge technology that can provide extremely accurate and reliable expression data to support drug discovery research. The versatile Agilent SureScan Microarray Scanner system provides the ability to scan genome-wide microarray profiles. For quality assessment of purified RNA and DNA, there are two instruments that include the Biorad Experion™ Automated Electrophoresis Station and Agilent 2100 Bioanalyzer. The Biorad CFX96™ Touch Real-Time PCR Detection System provides highly-reliable quantitative individual gene transcription profiling. Functional analysis of proteins using biochemical assay can be evaluated with the Perkin Elmer EnVision® Multilabel Reader. An ultimate high-throughput high-content imaging instrument, Operetta from Perkin Elmer can provide high resolution images for screening drugs under live and fixed cell context. Live cell metabolic changes with respect to oxygen consumption and pH change due to respiration can be determined using Xfe 96 extracellular flux analyzer exclusively from Seahorse.

Equipment

Agilent SureScan Microarray Scanner System


The SureScan Microarray Scanner is a state-of-art, laser-induced fluorescence scanner designed to read microarrays printed on standard 1” × 3” slides. The SureScan scanner measures the fluorescence intensity of labeled sample nucleic acid (DNA and RNA) bound to microarrays. Data extraction is handled by the Feature extraction program available on the connected computer.

Scanner capabilities:

  • Scan CGH, CGH+SNP, ChIP-on-chip, DNA methylation, microRNA arrays with dual color and up to 3 microns sensitivity
  • Feature extraction software extracts data from scanned images.

Operating and Handling Procedures

Investigator designs and runs their microarray slide hybridization protocol. For hybridization of the slides, core houses a hybridization oven with adjustable temperature for investigator use.

Scheduling to scan slides on the Agilent Surescan Scanner is done with our online scheduler. Slides can be scanned by the core personnel as per the investigator protocol.

Sample quality control:

DNA and RNA samples quality of purity can be evaluated using either BioRad Experion or Agilent Bioanalyzer available in the core facility.

Data storage and retrieval:

All generated data is stored online on university server in user specific folder, which is to be set up before their first use. Local data transfer can be done using storage devices like USB stick or external hard drives.

Data analysis:

Data extraction can be done with the Feature extraction software that is provided in the accompanying computer.

Data Retention policy:

Data will be stored for 1 year from the collection date on the server. It is the investigator responsibility to store their data after this time period.

Biorad Experion™ Automated Electrophoresis Station and Agilent 2100 Bioanalyzer


The Experion Automated Electrophoresis Station performs all the steps for gel-based electrophoresis in one compact, durable unit. The Experion Automated Electrophoresis System can be used upstream and / or downstream of a number of nucleic acid- and protein-applications.

The Agilent 2100 Bioanalyzer is a microfluidics-based platform for sizing, quantification and quality control of DNA, RNA, proteins and cells.

Equipments capabilities:

  • DNA / RNA / Protein purity analysis

Operating and Handling Procedures

Scheduling for the equipment can be done with our online calendar for Experion and Bioanalyzer. Individual user designs and runs their protocol, however new protocols designed are done with core personnel. All reagents and plastic wares are to be provided by the user.

Data storage and retrieval:

All generated data is stored online on the university server on user specific folder, which is to be set up before their first use. Local data transfer can be done using storage devices like USB stick or external hard drives.

Data analysis:

Data analysis is done with the Experion manager or 2100 Expert installed on their respective computers. It is also possible to export data to excel file for further analysis.

Data Retention policy:

Data will be stored for 1 year from the collection date on the server. It is the investigator responsibility to store their data after this time period.
