Expression Profiling with Microarrays
Description
Microarrays are important tools for profiling gene expression, and are based on complementary binding between probes that are attached to glass chips and nucleic acids derived from samples. Using these arrays, scientists can simultaneously evaluate the expression of thousands of genes. In addition, the expression profiles of...

Transcript
DNA microarrays are widely used tools to simultaneously measure the expression of many different genes. They consist of thousands of probes—each representing a different gene—immobilized on “chips” or slides, and rely on complementary hybridization to evaluate gene expression in different biological conditions.
