The final week of February, 2019 (Feb. 25 - Mar 1), iLab Operations Software will be conducting an internal event and will be staffed at significantly reduced levels. iLab Support will prioritize critical issues first (i.e. issues that prevent key workflows from completing) and to escalate an issue, please add "Urgent" to the ticket/ email subject or press "1", when prompted, on the iLab Support phone (regional numbers can be found here). Regular support tickets will be monitored periodically and processed in order of submission starting March 4th, 2019. During this time, you can also refer to the iLab Help Site and iLab Status Page for site information. Please note that this will not affect standard Core Facility Operations.

  • Isolation of nucleic acids from biological specimens
  • Quantity and quality assessment of nucleic acids (Nanodrop spectrophotometer and Agilent Bioanalyzer)
  • Epstein-Barr Virus transformation of lymphocytes to establish lymphoblastoid cell lines 


  • High throughput genotyping of single nucleotide polymorphisms (SNPs) using Illumina Omni BeadChip arrays
  • TaqMan allelic discrimination analysis using the ABI 7900HT Sequence Detection System

Whole Genome Gene Expression

  •  Whole genome gene expression microarray analysis for human (Illumina HT12 BeadChip) and mouse (Agilent Mouse GE 8x60K microarray)
  •  Targeted gene expression analysis using the TaqMan real-time quantitative PCR method and the ABI 7900HT Sequence Detection System
