GENE EXPRESSION CHIPS Meaning and
Definition
-
Gene expression chips, also known as DNA microarrays or gene chips, are a high-throughput technology used in biological research and molecular diagnostics. These chips provide a comprehensive analysis of gene expression by simultaneously measuring the levels of thousands of genes within a biological sample.
At its core, a gene expression chip is a solid substrate, usually a glass slide or a silicon wafer, containing a vast array of microscopic spots known as probes. Each probe corresponds to a specific gene or gene fragment. These probes are designed to hybridize, or bind, with specific complementary sequences of messenger RNA (mRNA) molecules found in the sample under investigation.
The process of gene expression begins with the isolation and purification of mRNA from a biological sample. This mRNA is then labeled with a fluorescent marker and applied onto the chip, allowing the labeled mRNA to hybridize with its corresponding probe. The chip is then scanned, and the fluorescent signals emitted by the labeled mRNA molecules are captured and converted into data that reflects the abundance of each target mRNA in the sample.
This data can then be further analyzed using statistical methods and bioinformatic tools to unravel complex gene expression patterns, identify differentially expressed genes, and gain insights into various biological processes and diseases. Gene expression chips have proven to be invaluable tools in genomics and have helped revolutionize fields such as cancer research, drug discovery, and personalized medicine.
