Specific information is available on BACs, ESTs, overgos, and SSRs.

Simple Probe Search

This search form allows you to just enter basic name info to quickly retrieve the desired probe. Use % as a wild card.

The above search will find myb-related probes. Another interesting search is %csh, which will find probes developed at Cold Spring Harbor.

This search can be executed on every page on the site by utilizing the form in the upper right corner. Choose "probe" from the drop-down menu, enter your search term in the field, and hit return to find the probe you're looking for.

Overview of Probe Data

Currently, the probe data set contains a mix of both probe and sequence information. Within this set of data you can find:

+ SSRs
+ Overgos
+ ESTs
+ BAC clones
+ AFLPs
+ non-EST cDNAs
+ DNA probes
+ genomic DNA
+ MITEs (miniature inverted repeat transposable elements) (see all MITEs)
+ RAPDs
+ YACs (yeast artificial chromosomes) (see all YACs)
... and a small assortment of other types.

ESTs, BACs, SSRs, and Overgos can be searched specifically through their respective search pages.

Discussion of Probe Data for the General Public

What is a probe?

A probe is a sequence of DNA (or RNA) that can be used to identify, usually through autoradiography, specific DNA or RNA molecules bearing the complementary sequence.

What is the value of storing and studying probe data?

Maintaining a warehouse of probe information makes it easier for researchers to find and use a particular probe when they want to study a specific piece of DNA or RNA.

What is the connection between corn and probe data?

Using probes, specific pieces of corn DNA can be studied, increasing our understanding of how the corn plant works on a piece by piece basis. We can use the knowledge of what each piece of DNA does to improve the corn plant.
