The Microarray Data Analysis Process

microarray data analysis process

In the laboratory, a microarray gene expression experiment involves:

From then on, analysis of the data is done on computers:
  1. The spots (or "Features") representing the various genes on the array ("Reporters") are measured using image analysis software. Average intensity, background intensity, and other parameters are recorded.
  2. Measurements from many array images are collected together.
  3. The collected data is analyzed to find genes with similar expression patterns, cell types with similar patterns, etc.
  4. The results are presented in some way that makes it easier to study them.
