Dynamic gene expression profiling market revealed in Percepta Associates’ new Gene Expression Profiling Life Science DashboardTM market research report.

Carlsbad, Calif. – April 29, 2008 — Today Percepta Associates Inc. announced the release of Series Two of its Gene Expression Profiling Life Science DashboardTM market research report. Drawing comparisons to the findings of Series One published in February 2007, Percepta reports measurable shifts in market share within this market. Percepta’s survey of active global life science researchers revealed that Applied Biosystems (NYSE: ABI) and Bio-Rad Laboratories (AMEX: BIO) have enjoyed the greatest gains in overall market share in the largest expression profiling segments. Affymetrix (NASDAQ: AFFX) remains the strong leader in its primary market segment, microarray-based expression profiling, but other companies appear to be making headway. Invitrogen (NASDAQ: IVGN), Agilent Technologies (NYSE: A), and Roche Applied Sciences (VTX: ROG.VX) are among other companies that experienced market share changes in 2007. Contributing to these market dynamics is an increase in nearly all segments in researcher’s desire to switch gene expression product suppliers for a variety of performance or service reasons.

Product segments analyzed in Series Two of the new Gene Expression Profiling Life Science Dashboard™ include:

  • Microarray-based gene expression analysis
  • Serial analysis of gene expression (SAGE)
  • Differential gene expression analysis using multiplex PCR
  • qRT-PCR analysis using gene specific probes
  • qRT-PCR analysis using SYBR Green
  • Northern Blot analysis
  • Transcriptome studies using tiling arrays (new in Series Two)
  • Transcriptome studies using short read sequencing (new in Series Two)

Gene expression profiling methods enable the detection and measurement of multiple expressed gene
transcripts in a single RNA sample. Continually evolving methods, such as microarray analysis, multiplex PCR and quantitative real-time PCR, are integral to deciphering the molecular mechanisms involved in gene function, biological development and disease progression, and are important tools in the discovery and development of new drug targets and diagnostic biomarkers.

“The expression profiling market churn observed in this market research report illustrates how the
genomics market will be changing as new technologies are embraced that enable researchers to integrate genetic analysis methods more cost effectively and extract even more information from a single sample.” said Scott Provost, Principal at Percepta. “The most successful life science market suppliers will monitor the early market indicators, anticipate change and rapidly make the strategic adjustments needed to secure market leadership. The Life Science DashboardTM series was designed to support this process.”
