Welcome to Johns Hopkins Deep Sequencing & Microarray Core Facility
Our aim is to provide cost-effective and time-efficient access to cutting-edge genomic technologies and expert assistance with experimental design and data analysis.
Our current service portfolio includes the following categories:
-NextGen Sequencing: we offer library constructions, for Illumina HiSeq and MiSeq NextGen sequencing platform; and for various applications: mRNA-seq, ChIP-seq, Single Read, Paired-End Read, Mate-pair, Targeted Resequencing using Agilent Sure-Select Technology,Microbiome 16S rRNA sequencing, and barcode multiplexing. We also offer complete service from library construction, through sequencing, and data analysis.
-Third Gen Sequencing: We offer library preparation, sequencing, and data analysis on PacBio RS Single Molecule Real-Time (SMRT) sequencing platform. Such services includes short circular consensus sequencing for high accuracy for validating SNPs identified using other technologies, for determining mutation linkages, long reads sequencing for identifying potential new transcript isoforms, fusion genes, and chromosomal structure variations, and for helping sequence mapping with short reads especially for sequencing through regions with repetitive sequences. The techonology is also excellent for de nove assembly small genomes, with the new 150K upgrade, a single library and a single smrtcell run can assemble a complete bacteria genome.
-Microarray: We offer multiplatform microarray services including Affymetrix, Agilent, and Roche/Nimblegen. Our instrumentation for microarray analysis include two Affymetrix GeneChip Systems with autoloaders (capable of autoscanning 48 GeneChips each), four fluidic stations, two Affymetrix hybridization ovens, four BioMicro MAUI Hybridization Stations for regular slide microarray hybridization, Axon GenePix Scanner, Agilent′s most advanced 2-Micro Scanner, Agilent hybridization oven and a Robbins Scientific 400 Oven fitted with a rotator for Agilent hybridization chambers. We offer microarray services from all these companies on all their catalog arrays and custom arrays.
-Nanostring: We offer the Nanostring nCounter Analysis services for multiplexed gene expression, miRNA expression, and copy number variation analysis. The nCounter Analysis System utilizes a novel digital technology that use single molecule imaging to direcly counts the molecules without relying on enzymatic amplification. It requires a small amount of samples and offers high level of precision and sensitivity.
-DNA, Chromotin, and RNA shearing: The core offers sample shearing services using either Covaris E210 instrument or Hydroshear instrument. The Covaris instrument uses ultrasonic wave with defined wavelength and Adaptive Focused Acoustics (AFA) technology to efficiently shear DNA, chromatin, or RNA to size distributions less than 1.5 kb. Covaris is often used for library construction for short read sequencing. The hydroshear is excellent for shearing DNA to a narrow size distribution with peak size larger than 2 kb.
-Data analysis: We offer statistical and bioinformatic data analysis on primary data and downstream functional analyses. We support data from our and other, outside, platforms; and can help with publication and database submission. We also provide commercial software at affordable rates for general use on our workstations or your own machine, either by subscription or by the hour. These software packages include Partek®, Spotfire®, and Ingenuity® Pathway Analysis, and CLC bio® Genomic Workbench and Genomic Server.
In addition, we also offer free pre-experimental consultation to ensure your study to be as successful as it can be, as economical as possible (we KNOW it's expensive!) and most importantly, as scientifically rewarding as possible.
All data generated from the core are stored in a confidential database and are accessible through core ftp server. Data and information supplied by the Core are intended for research use only. This facility is not certified to supply data to be used in clinical care.
The JHMI Deep Sequencing and Microarray Core Facility is located on 3rd floor of Miller Research Building (MRB), formerly known as Broadway Research Building (BRB), in Room 351, and the lab in Room 360, just across the hallway. The core has been in operation since 2002 and has supported research projects from more than 200 principle investigators and 300 individual researchers. The core was initially funded by support from
- The School of Medicine Office of the Dean
- Institute of Cell Engineering (ICE)
- Institute of Basic Biomedical Sciences (IBBS)
- McKusick-Nathans Institute of Genetic Medicine (IGM)
with startup funds, space, and personnel. Currently, the core is operating under a cost-recovery basis and it is our goal to keep user fees as low as possible in order to encourage the utilization of the core by the Hopkins and regional research community.

CLC Genomics Server and Workbench: Thanks to the generosity of CLC Bio, we have installed CLC Genomics Server and CLC Genomics Workbench on a trial basis for analyzing NextGen sequencing data. The Genomics Workbench runs on Macintosh, WIndows and Linux computers, and it imports data from SOLiD, Illumina, 454, and Helicos. Functions in the Workbench include, quality and adapter trimming, de novo assembly, reference assembly, RNA-seq, ChIP-Seq, SNP and DIP detection, and a suite of functionality for microRNA analysis. The Genomics Server allows you to analyze your data with the tools from the Genomics Workbench, but on a remote machine, one with much greater processing power, such as our new server. The Genomics Workbench accesses the Genomics server as a thick client, so you can process your data from your office, but much more efficiently than your desktop computer can. For testing out the CLC Genomics Server or Workbench, please contact Conover Talbot Jr. or Haiping Hao.
