The Wistar Genomics Facility serves as a hub for consultation and scientific interactions relating to nucleic-acid based methods and provides expertise and support to insure the best possible use of emerging nucleic-acid technologies.
In addition to consultation and collaboration with Wistar Cancer Center members, the Facility provides services to the greater scientific community.
The establishment of this facility was supported in part by an NCI Cancer Center Support Grant and equipment grants from the Commonwealth of Pennsylvania, The Pew Charitable Trusts and the National Cancer Institute.
"The ABI 3130xl is a 16 capillary machine that can sequence over 100 samples/day. The 3100xl can also be configured for fluorescent fragment detection and microsatellite analysis and is equipped with Gene Scanning Software."
"The Agilent 2100 Bioanalyzer is a microfluidics-based platform for sizing, quantification and quality control of DNA, RNA, proteins and cells. Results are delivered within 30-40 minutes in automated, high quality digital data.
Miniaturization of analytical instrumentation has many advantages over conventional techniques. These advantages include improved data precision and reproducibility, short analysis times, minimal sample consumption, improved automation and integration of complex workflows. Launched in 1999, the Agilent 2100 Bioanalyzer was the first commercially available instrument to use microfluidics technology for the analysis of biological samples. Today, the Bioanalyzer offers a broad range of pre-validated analysis kits combined with an easy-to-use benchtop system."
"ImageQuant LAS 4000 is a digital imaging system for sensitive, quantitative imaging of gels, blots, and colonies. ImageQuant LAS 4010 Fully equipped imager that in addition performs ultraviolet (UV) and visible (RGB) fluorescence imaging."
The Illumina BeadStation 500GX has an autoloader, manual and DASL options. Infinium whole genome genotyping can be carried out on the BeadStation.
"Illumina’s Genome AnalyzerIIx is a proven platform for genetic analysis and functional genomics, and has transformed the way experiments are developed and executed. Massively parallel sequencing technology leverages clonal cluster formation and proprietary reversible terminator chemistry to dramatically improve the speed, and reduce the cost, of large-scale sequencing."
"The Genome AnalyzerIIx supports a wide range of applications, including whole-genome and candidate region resequencing, transcriptome analysis, small RNA discovery, methylation profiling, and genome-wide protein-nucleic acid interaction analysis."
"The Qubit® 2.0 Fluorometer is Life Technologies’ second generation fluorometer designed to work seamlessly with our highly specific and sensitive Qubit® DNA, RNA, and protein quantitation assays."
Available upon request
ABI OpenArray miRNA assay is available for human and mouse plates. OpenArray digital, pathway specific PCR and custom miRNA and gene expression assays are available upon request.
"The facility uses an ABI 3130xl capillary machine for Sanger-type sequencing with fluorescently-labeled dye-terminators, the ABI four-color detection, and sequence analysis system."
"Purified DNA is provided by the investigator with an order form specifying the quantity, form (double-stranded, single-stranded, or PCR product) and estimated size of the DNA. It is essential that the size and concentration of PCR products are determined accurately prior to sequencing. Lambda or Bac clones require submission of greater quantities of DNA."
"For each sequencing run, investigators must provide in numbered or labeled 1.5 ml Eppendorf tubes:
Double-stranded DNA: 1-1.5 µg of purified DNA at 0.2-0.25 µg/µl
Single-stranded DNA: 1 µg of purified DNA at 0.1-0.125 µg/µl
PCR products: at least 15ng of purified DNA per 100 bp of PCR product in 5ul water
Lambda phage or Bac clones: 10ug purified DNA at 2-2.5 µg/µl
A name designation of 8 or fewer characters and the primers to be used for each run must be clearly indicated on the submission form.
M13 forward, M13 reverse, T7, T3, and SP6 primers are provided by the Facility at no additional cost. Specific primers must be supplied by the investigator at 3.2 pmoles/µl.
Microsatellite Analysis: at least 450ng of DNA at 30ng/ul for 5 loci assay, and 10ng of DNA at 0.125ng/ul for 16 loci assay.
Depending on well availability, DNA samples delivered by 11:00 am will be available the next day at 3:00 pm."
"For clean double-stranded templates, extremely accurate sequence reads of >=600 bases are obtained routinely. Text files of sequence data are e-mailed. The original result folder from the ABI base caller is placed in a computer folder for electronic retrieval if needed.
Other modes of delivery can be arranged."
DNA isolation using Tri-reagent.
