Gene Chips for Comparing Cell Activity

DNA microarrays are gene chips used to compare gene activity in different conditions. They are high-throughput assays, which means they can analyze large amounts of data at once. They are also relatively inexpensive and can be automated, making them useful for genome-wide studies.

These chips are...

A DNA microarray contains thousands of single-stranded DNA probes arranged in a grid on a glass or silicon chip. The DNA of interest is fluorescently labeled and can hybridize to its complementary probe on the microarray.

This technique allows the simultaneous measurement of the relative concentrations of specific cDNA sequences.
