Microarray Gene Expression Analysis: Cancer vs Normal Cells #177351 (License: Personal Use)

The diagram shows RNA isolation from cancer and normal cells, followed by reverse transcription into cDNA labeled with red or green fluorescent dyes. The labeled targets are combined and hybridized onto a microarray chip, where fluorescence intensity reveals up- or down-regulated genes. Spots appearing yellow indicate co-expression, while red or green spots reflect cancer- or normal-specific expression.

Used in molecular biology educational resources, research presentations, and biotech websites to explain transcriptomic profiling; matches user intent for learning about gene expression techniques or cancer biomarker discovery.
