NanoDrop ND-1000, NanoDrop One Microvolume UV-Vis Spectrophotometer, and Qubit Fluorimeter: These spectrophotometers allow micro-level quantitation of 1 µl of sample with high reproducibility. This allows sample measurement up to 50-fold higher in concentration than can be measured on classical 1 cm cuvette-based systems, virtually eliminating the need for dilutions. The NanoDrop One instrument provides more accurate determination of quantity and quality of DNA, RNA, and protein samples in seconds with 1-2 µl, including full-spectral data. This instrument offers more dynamic range (0.2-27,500 ng/µl dsDNA), greater wavelength range (190-850 nm), and higher spectral resolution. The Qubit Fluorimeter is a fluorescence-based system. DNA or RNA concentration is reported by a dye that emits a signal only when bound to the target, which minimizes the effects of contaminants such as degraded DNA or RNA.

- QIAxcel Advanced System:
The QIAxcel Advanced system provides high-throughput RNA and DNA analysis (up to 96 samples) using capillary based gel system. It allows for more efficient quality control of RNA and will serve as a replacement for standard agarose gel electrophoresis genotyping of PCR products. Thus, for most genotyping, the preparation of agarose gels, ethidium bromide staining, and image analysis will no longer need to be done. Additionally, the system can be configured to automatically call genotypes.

- Perkin Elmer Zephyr G3 NGS Workstation: The Zephyr® G3 NGS
Workstation is a benchtop liquid handler designed to automate library preparation for next generation sequencing and address laboratory requirements for the physical separation of pre and post-PCR processes. The graphical user-interface and standardized deck with integrated hardware maximizes laboratory productivity while reducing variability resulting from manual pipetting steps. The workstation offers a walk away solution and flexible processing enabling the parallel processing of 8-96 NGS library or exome preparations or a 96-well plate of SPRI size selections / post-PCR clean-ups per run.

Medium throughput genetic/genomic analysis instrumentation |
Bio-Rad CFX96 and Bio-Rad CFX384 Real-Time PCR Detection Systems: These systems provide medium-throughput platform (n=1-384 samples) to perform gene expression/quantitative real-time PCR. These systems allow for quick set-up of runs and monitoring of amplification traces in real time on the integrated LCD touch screen. The CFX384 allows up to five-target detection and easy-to-use software to calculate fold-change between sample groups.

- Illumina MiSeq platform: The Illumina MiSeq platform is a desktop
sequencer that can produce 2 x 300 paired-end reads in a single run and generated 15-20 Gigabases (Gb) or up to 50 million sequencing reads in a single run. This allows small genome sequencing and assembly, and enables detection of target variants with unmatched accuracy. In addition, this system is perfectly suited to perform 16S microbial sequencing on up to 384 pooled samples, amplicon sequencing, and genotyping by sequencing of several hundred samples on a given run. - Specifications

- 10X Chromium Single Cell Instrument: The 10X Chromium
Instrument enables the capture of individual biomedical material, such as DNA fragments or whole cells within tens of thousands of uniquely addressable partitions, each containing an identifying barcode for downstream analysis. The most important utility of this instrument is to perform single cell RNA sequencing (scRNAseq). scRNAseq has become an important research tool (both for basic science and clinically) allowing for simultaneous transcriptome analysis on individual cells/different cell types derived from complex tissues as opposed to performing sequencing on RNA isolated from an entire piece of tissue or even cell-culture studies. For example, an entire organ (e.g. kidney, brain, etc.) can be harvested, digested into a single cell suspension, and sequencing performed on 100- 80,000 individual cells. An added benefit of this technology is that it fully integrates with our current Illumina sequencing equipment, including the Illumina NextSeq 500 and 2000.
