About Our Microarray Data and What's Coming

We provide documentation and data for the microarrays produced by the Maize Gene Discovery Project. This data includes details on what the arrays consist of, what can be found at each location, and connections to the related sequence data.

Ordering Arrays Microarrays generated by the Maize Gene Discovery Project can be ordered from Dr. David Galbraith's lab at the University of Arizona. Please request slides by email at zmarrays@ag.arizona.edu. The charge for each set of library slides is $150; the charge for each set of Unigene slides is $200. Each set contains two identical microarray slides. Orders will be filled on a first-come, first served basis. For more information, please contact Dr. Galbraith or read our documentation. Please allow 4-6 weeks for delivery. You will receive a bill separately from the University of Arizona. The charges are levied to pay the cost to array newly sequenced, verified samples.

If you are looking for other maize microarrays, try searching PlexDB!


Microarray Element Search

Microarray Element Search Criteria

This form can be used to locate specific microarray elements from the Maize Gene Discovery Project microarrays. We have a great deal of documentation on these arrays as well, for those unfamiliar with them.

You can use % or * as a wildcard in the text field.

Discussion of Microarray Data For The General Public

What is a microarray?

A microarray is a small slide containing thousands of DNA samples. These samples are usually chosen to be complementary to interesting genes or to unknown genes. These slides are well-documented, as you can find the sequence and other known information about each sample on the slide. Then, DNA from known samples (for example, a sick maize plant) is spread over the surface, and matching DNA binds to the slide, while non-matching DNA does not. We then just look for the places where the DNA has binded together to identify the genes we're interested in.

Microarrays thus allow for high-throughput genetic experiments to be done very quickly, with thousands of comparisons done in mere hours when previously it would take years and years to complete such an experiment.
