Genome-wide expression studies use DNA microarray assays to detect the locations of proteins produced by cells.
DNA microarray is a technology used to view the order of nucleic acid sequences in a certain location and can be used to analyze thousands of samples simultaneously.
Microarray applications are often used in cancer detection, where cancer cells have abnormalities in their gene expression. This technique also makes it possible to determine the developmental stage of cancer cells by comparing their expression levels with specific probes already present on the microarray.
