Next Generation Sequencing Services

Ion Torrent Proton

With the Ion Torrent Proton, libraries can be templated and sequenced in two days. Templated library sequences are amplified on Ion Sphere Particles and checked for quality. An enrichment step purifies the amplified template, and sequencing is performed using Ion Torrent's semiconductor ion chips. During this process, nucleotides are sequentially incorporated into DNA, causing a hydrogen ion to be released. Detection of the voltage change allows for genotypic calls to be made. With the Ion Torrent™ Proton P1 chip, 200 bp single end sequencing can provide up to 80-100 million reads per run. On-campus customers can undergo training to become certified to run the instrument themselves. More information on sample submission and Ion Torrent Sequencing chips is available on the FAQ page.

NGS Library Preparation and Quantification

The certified on-campus users can do library preparation and quantification with Ion Torrent platform.

Ion Torrent preparations available: Ion Xpress Plus Fragment Library and Ion Total RNA-Seq.

After preparation, libraries are quantified to ensure proper loading of the library. Users can quantify libraries by Bioanalyer or RT-PCR using the KAPA library quantification kits.

High Throughput Nucleic Acid Manipulation

Plant DNA Extraction:

GTF provides high throughput DNA Extraction using the Qiagen BioSprint96. Qiagen DNA Extraction is suitable for Ion Torrent or Illumina Sequencing and Sequence Capture. Once the lysate is prepared, a single plate can be extracted in 30 minutes. Extraction can be conducted by on-campus customers who undergo training to become certified to run the instrument themselves. Grinding and quantification services are not included in the price of a run, but GTF can provide this service for an additional fee. Certified users must provide their own pipets and tips. The BioSprint is available to customers for use 8 AM to 5 PM Monday through Friday when the University is in session. Please contact GTF staff if services are required outside of these times. User Forms are available to be printed and filled out prior to your scheduled appointment in the GTF or a printed copy is available by the instrument to be filled out at the time of your appointment.

Plant RNA Extraction:

GTF provides high-throughput RNA Extraction using the Qiagen BioSprint96. With the BioSprint, 96 samples can be extracted in 30 minutes. BioSprint extraction can be conducted by on-campus customers who undergo training to become certified to run the instrument themselves. Grinding and quantification services are not included in the price for a run, but GTF can provide this service for an additional fee. Certified users must provide their own pipets and tips. The BioSprint is available to customers for use 8 AM to 5 PM Monday through Friday when the University is in session. Please if services are required outside of these times. User Forms are available to be printed and filled out prior to your scheduled appointment in the GTF or a printed copy is available by the instrument to be filled out at the time of your appointment.

Eppendorf AF2200 Plate Reader:

GTF offers the AF2200 Plate Reader for nucleic acid quantification in a high-throughput format. The Eppendorf µPlate 0.5 is available for measuring the absorbance of small volume samples. GTF supplies both absorbance and fluorescence filters for use. Users must provide their own supplies and consumables (pipets, tips, tubes, plates, reagents, etc.). The Plate Reader is available to customers for use 8 AM to 5 PM Monday through Friday when the University is in session. Please contact GTF staff if services are required outside of these times.

PCR Instruments

Real-Time PCR Systems:

The GTF provides one quantitative real-time PCR machines for customer use: The Roche LightCycler 480 Real-Time PCR system. The Machine is available to customers for use 8 AM to 5 PM Monday through Friday when the University is in session. Please contact GTF staff if services are required outside of these times. A one-hour training session with GTF staff is required for new users. Users must provide their own supplies and consumables (pipets, tips, tubes, plates, reagents, etc.). Sign up for time in the scheduler's page. User Forms are available to be printed and filled out prior to your scheduled appointment in the GTF.
