Primary goals
Primary Goals

  • To provide investigators with high quality, state-of-the-art gene expression profiling & genotyping services in a timely fashion using the affymetrix platform

    • rigorous standardization of protocols and multiple quality control checks

  • To provide streamlined data analysis and identify signature genes

    • Application of complex statistical tools

New Service Initiatives

  • Taqman Low Density Arrays (can analyze 8 samples for 24 different genes)

  • Exon and Tiling Array Mapping

  • Method development for the isolation and analysis of picogram amounts of RNA in collaboration with bio-tech companies

  • Service for non NHLBI investigators at a nominal cost

Core policies
Core Policies

  • Investigator has to provide chips and samples to the core (We need at least 2µg total RNA in 4µl volume, 250ng genomic DNA)

  • Submitted RNA/DNA samples should be of good quality

  • Description of project / sample information

  • It is advisable to have an n of 5-6 for each group to have a good statistical power for analysis

  • If you have only one or 2 samples per group, the core wont be responsible for data quality

  • Turn around time is 2 weeks since the receipt of samples

  • You will be notified by email the status of your project and upon completion will send you QC data

  • If a problem arises with the analysis of one or more of your specimens, you will be contacted immediately
