What Is LabKey Server?
An open-source, web-based platform for
organizing, analyzing & sharing scientific data
Data integration analysis for assays
Proteomics, flow cytometry, plate-based assays, etc.
Study Data Management
Combines demographic, clinical, assay & specimen data
LabKey Server powers many deployments…
CPAS: FHCRC proteomics repository
Atlas Science Portal: SCHARP’s HIV vaccine studies
AdaptiveTCR: Customer analytics for ImmunoSEQ NGS
UW (Katze, Heinecke, et al), USC, Markey, Harvard,
IDRI, TGen, Wisconsin Primate EHR, UC Denver, etc.

Importance of MHC Class I
Host Immune
Genetics

Reviews Immunology 2003
MHC class I molecules
dictate immunity to
disease
High degree of
polymorphism within
the MHC class I
peptide-binding
domain
Specific MHC alleles
associated with
superior control of HIV
infection
Importance of Viral Variability
HIV has fast
replication cycle, high
mutation rate
Evolution of the virus
causes escape from
immune responses
Specific mutations are
associated with
resistance to
antiretroviral drug
therapy

Sequencing in the O’Connor Lab
 2005 – 2009 Sanger sequencing
 “Prohibitively expensive” for most experiments
 2009 Roche/454 GS FLX at UIUC
 2010 Roche/454 GS Junior in lab
 Roche/454 GS Junior




Long-read instrument, critical for genotyping
Identical to GS FLX, but 1/8 throughput & lower cost
~100,000 reads per run (~1¢ per read), average ~560bp read length
115 runs this year
 MID tagging
 Allows pooling multiple samples (30-100) into a single run
 Galaxy server
 Open-source sequence analysis tool (Giardine et al, Genome Res 2005)
 Lab has built custom workflow to match sequences to known MHC alleles
 Uses BLAT, transitioning to AGILE (Northwestern alignment tool)

Roche/454 MHC Workflow
• Total RNA isolation and cDNA synthesis
– RNA isolation ~4 hrs; cDNA synthesis ~2 hrs
• Primary PCR amplification
– plus SPRI purification, quantification, pooling ~3 hrs
• emPCR
– set-up ~1 hr, run ~5.5 hrs
• Breaking and enrichment
– ~3 hrs
• Roche/454 GS Junior run
– set-up ~1.5 hrs; run time ~10 hrs
• Data processing and analysis
– run processing ~2 hrs; analysis time varies

There is a real disconnect between the ability to
collect next-generation sequence data (easy)
and the ability to analyze it meaningfully (hard)

PROBLEM: DATA
MANAGEMENT!

Problem: Data Management
 As volume has increased, lab has found it difficult to
manage all their sequencing data & meta data:
 Run meta data
 Run metrics
 Sequencing reads and quality scores
 Sample information and multiplex identifiers (MIDs)
 Reference sequences for genotyping experiments
 Genotyping matches
 O’Connor asked LabKey to build a system that can:
 Store sequencing and genotyping data in a single database that
links all the tables, allowing arbitrary queries and reports
 Provide tools for analysis, querying, visualization and export
 Automate data workflows for efficiency & consistency
 Eventually, link sequencing results to their primate EHR system
