GO (Gene Ontology) Search is a specialized search tool that retrieves Expression type probes based on GO term(s) that you specify. GO terms are a controlled vocabulary that classifies gene products using a common language. The terms focus on the function and biological context of gene products. A Gene Ontology (GO) Search is thus a good way to identify probes for genes and gene products that are associated with biological processes, molecular functions, and/or cellular components that you want to study.
GO Search searches for probes using GO terms, not GO IDs. You can specify all or part of a GO term, or multiple GO terms separated by pipe "|" characters, and retrieve all the active probes associated with the selected GO terms. For example, all of the following are valid search strings:
DNA-directed RNA polymerase activity
polymerase
Cytoplasm|Nucleus|Microtubule cytoskeleton
eArray can also help you find valid GO terms for your probe search. See How to do GO Search.
eArray gives you the option to do an Exact Search for probes associated with GO terms.
Exact Search is a GO Search option. In an Exact GO Search, eArray searches for probes associated with GO terms that perfectly match the text string in the GO Term text box. For example, a search with the text string intracellular protein transport in the GO Term text box returns only probes associated with the specific GO term intracellular protein transport.
If the Exact Search option is not selected, then eArray searches for probes associated with GO terms that contain the specified text string anywhere within the GO term. For example, a search with the text string intracellular in the GO Term text box returns probes associated with the GO terms intracellular cyclic nucleotide, intracellular protein transport, intracellular signaling, and so on.
