The technique relies on the relative quantification of m RNA expression in cells or tissues.
Circulating blood cells can be used as an alternative to tissue biopsies when these are not available.
Both platforms consistently underestimate the relative changes in m RNA expression between experimental and control samples.
The bias observed with c DNA arrays was predictable for fold-changes We describe detailed protocols and results with an integrated platform for studying relative transcript expression, including microarray design and fabrication, analysis and calibration algorithms, and high throughput quantitative real-time PCR.
This approach optimizes sensitivity and accuracy while controlling the cost of experiments.
A high quality c DNA array was fabricated using a restricted number of carefully selected transcripts with each clone printed in triplicate.

Please use the feedback form and provide a detailed description of the problem.Overall, significant correlation was observed between microarray and q PCR results (ρ=0.708, p), array averaging, tissue type, and tissue preparation was assessed.Filtering of microarray data for measures of quality (fold-change and ρ-value) proves to be the most critical factor, with significant correlations of ρτ;0.80 consistently observed when quality scores are applied.
