SERVICES & INSTRUMENTATION
The GBCF offers the following services:
Next Generation Sequencing
The Genomics Laboratory operates several illumina platforms to support diverse sequencing applications:
Suitable for small-to-medium scale sequencing, method development and pilot projects. It provides accurate and timely data using illumina’s
Sequencing-by-Synthesis chemistry.
There are a variety of sequencing cartridges that come with the MiSeq which deliver different read lengths providing several options for the user. In addition, it offers the option of single or paired end reads to match your experimental needs.
Offers a comprehensive workflow offering compatible library prep kits, user-friendly setup, and integrated, onboard secondary analysis.
Gain access to a variety of applications including whole genome, single-cell, and whole-exome sequencing with the NextSeq1000 and NextSeq2000 sequencers
With the XLEAP Sequencing-by-Synthesis chemistry the Illumina NextSeq1000 and NextSeq2000 sequencers offer faster, higher quality, and higher throughput sequencing compared to the Illumina Miseq system. Depending on the sequencing cartridge used, the Illumina NextSeq1000/2000 has a data output range between 10-540Gb comprising about 100M to 1.8B single-end reads per run.
Third Generation Sequencing
The GBCF offers a variety of Oxford Nanopore Technologies (ONT) platforms for fast, reliable, and high throughput long reads sequencing.
These platforms can be applied in large genome projects, microbiome or metagenomics studies.
The MinION Mk1B is a powerful, portable sequencing device that delivers cost-effective and real-time access to gigabases of long-read sequencing data. The device is small enough to fit in a pocket and powerful enough to deliver up to 30 Gb data per experiment. It is useful for small-to-middle scale sequencing runs/projects.
The MinION Mk1C combines the real-time, rapid, portable sequencing of the Mk1B with a dedicated graphics processing unit (GPU) and the additional features of a smartphone, such as a cellular modem and touch screen.
This nanopore sequencer is a compact benchtop system offering on-demand sequencing with integrated real-time data processing. With the capacity to run five flow cells comparable to five MinION Mk1B experiments either concurrently or individually. Its integrated, high performance data processing alleviates the need for complex and expensive IT infrastructure.
A compact sequencer for two PromethION flow cells utilizing resources within the GridION or other suitable computational resources, such as workstations or laptops, to quickly enable accurate, high output nanopore sequencing. This allows up to two sequencing experiments to be run concurrently or individually.
Quality control of Nucleic Acids Analysis with Qubit Fluorometer, Agilent TapeStation, and LabChip GXII Touch HT
The Genomics Laboratory offers evaluation of nucleic acid concentration and size using the Qubit Fluorometer, Agilent TapeStation, and LabChip GXII Touch HT. These instruments provide quantitative measures of nucleic acid quality to proceed with other downstream applications.
See more on Quality control of Nucleic Acids Analysis
Qubit 4 fluorometer
The Invitrogen Qubit 4 fluorometer accurately and quickly measures the concentration of nucleic acids (DNA/RNA) and proteins. It can also be used to assess the integrity and quality of RNA.
The readings when measured are interpolated onto a standard curve. This device detects fluorescent dyes in Qubit assays that are highly specific to a target molecule of interest (DNA/RNA/protein) in your sample. It can also be used to detect either double- or single-stranded DNA molecules (dsDNA or ssDNA) even in the presence of RNA or common contaminants such as salts, free nucleotides, and proteins. The dyes used only emit fluorescence when bound to their targets, even at very low concentrations (~ 0.05 ng/ul) so the readings are highly sensitive. The reaction is rapid thus enabling absorbance measurements to be carried out within a few minutes.
Qubit Flex fluorometer
The Qubit Flex fluorometer applies the same features and technology of the Qubit 4 fluorometer but allows for simultaneous measurements of eight samples at a time. This makes it ideal for high throughput applications.
Agilent TapeStation
The Agilent 4200 TapeStation system is an established automated electrophoretic tool for DNA and RNA sample quality control. The system provides true compatibility for library preparation quality control within any next-generation sequencing (NGS) workflow.
The TapeStation boasts of a wide range of assays that can analyze fragments ranging from as low as 25 bp to more than 60,000 bp.
Assays require no more than 2ul per electrophoretic run, whether for RNA or DNA.
Sensitivity: 20 pg/ul – 100 ng/ul
LabChip GXII Touch HT
The LabChip GXII Touch HT system with its electrophoretic separation technology provides a complete solution, enabling the rapid characterization of both protein and nucleic acid with minimal sample input. It provides an automated alternative to the traditional methods while also providing increased throughput required by most genomic workflows.
The LabChip GXII Touch can perform a wide range of analysis in as little as 42 seconds per sample, delivering data comparable to traditional electrophoresis with as much as 70X increased throughput.
Our lab utilizes the system to determine the fragment sizes of libraries and their corresponding molarities prior to loading onto Next Generation Sequencing (NGS) platforms.
Nucleic Acid Extraction
The Genomics Laboratory has an automated nucleic acid extractor. The QIAcube HT System is a robotic workstation that provides fast and reliable automated high-throughput nucleic acid extraction and purification. It is quick, cost-effective and delivers high quality nucleic acids from 24-96 samples per run.
The QIAcube HT System offers
Sample types include tissue, cell, blood, stool and food material.
