Tulane Center for Translational Research in Infection & Inflammation ~ NextGen Sequencing Core


The Center for Transcriptional Research in Infection and Inflammation is now offering Illumina Next Generation sequencing services to support NGS based research studies of gene expression as well as single-cell RNAseq to the Tulane University research community.

The Sequencing Core has an interactive staff, dedicated to the production and delivery of high-quality sequence data.

  • Cell capture efficiency up to 65%
  • Compatible with Illumina® sequencers
  • More efficient than leading academic droplet systems


Illumina NexSeq 550


  • The NextSeq 550 System brings the power of a high-throughput sequencing system to your benchtop. With tunable output and high data quality, it provides the flexible power you need for whole-genome, transcriptome, and targeted resequencing.
  • mRNA sequencing (mRNA-Seq) enables researchers to take a closer look at gene expression and can be used to identify isoforms, novel transcripts, and gene fusions.
  • The NextSeq RNA sequencing solution leverages proven Illumina technology to deliver a detailed snapshot of the coding transcriptome. Sequence up to 16 transcriptomes per NextSeq run.


Bioinformatic Resoruces

Cypress is Tulane's newest HPC cluster, offered by Technology Services for use by the Tulane research Community.  It is a 124-node cluster, with each node providing dual 10-core 2.8 GHz Intel Xeon E5-2680 v2 CPUs, 64 GB of RAM, and dual Xeon Phi 7120P coprocessors. Nodes are interconnected on a 40 Gigabit Ethernet network using a single Dell Z9500 Ethernet Fabric Switch.

Cell Ranger V3.0 by 10x Genomics is run on cypress.  Cell Ranger is a set of analysis pipelines that process Chromium single-cell RNA-seq output to align reads, generate feature-barcode matrices and perform clustering and gene expression analysis.”  Cell Ranger data can be viewed interactively with the 10x Loupe Browser. Subsequent analysis is done in R using Seurat and Monocle packages.

Seurat is an R package designed for QC, analysis, and exploration of single-cell RNA-seq data. Seurat aims to enable users to identify and interpret sources of heterogeneity from single-cell transcriptomic measurements, and to integrate diverse types of single-cell data.

Monocle provides tools for analyzing single-cell expression experiments. Monocle introduced the strategy of ordering single cells in pseudotime, placing them along a trajectory corresponding to a biological process such as cell differentiation by taking advantage of individual cell's asynchronous progression of those processes.


The Sequencing Core is located on the 3rd floor of J. Bennett Johnston Building, Room 339 in the Center for Translational Research in Infection and Inflammation.

The core is currently accepting samples, for more information reach out to Jay Kolls or Kejing Song.
