Dual Array Method for Stress Analysis (447)

Graphic of Control Array Sample

Problem: Measure environmental stress effect on messenger RNA population (+ or -) with minimal processing steps.

Project Activity Scope (from Technical Overview Chart): Mechanisms through Sensors and Devices.

PNNL Solution:

  • Prepared 1st array to control sample
  • Exposed 2nd array to test solution
  • Analyzed each array
  • Formed difference data array by subtracting corresponding pixel responses on the two arrays (i.e. [Responsex,y(Control) - Responsex,y(Test)])
  • Pixel values indicate stress effects

Capabilities Employed to Meet Client Needs: Array preparation, hybridization, and data analysis.
