Using NetAffx Queries

NetAffx Query searches return probe sets matching your keywords, searching all the gene names, gene symbols, probe set ids, Gene Ontology (GO) and Medical Subject Heading (MeSH) terms, accession ids, sequence descriptions.

1. Quick Query
Quick Query searches are convenient and fast - just enter your keywords in the box. on the Standard query page, the Quick Query can be combined with your other searches as an "All descriptions" search.

Example Searches: These terms will return lists of probe sets that are related to the keywords, genes or probe set IDs.
liver receptor

2. Precision Searches with Standard Query
If QuickQuery is returning too many results, you should use the Standard Query Page to get precisely the probe sets you want.

Terms in the Standard Query Page have no wildcards by default.

Example Search:
A "Gene Symbol" Search for PRKC%
will find the probe sets which detect all isoforms of protein kinase C but a search of PRKC
will only find probe sets for the primary PRKC gene.

3. Wildcards on Standard Query Searches
Example Search:
will find all the isoforms of protein kinase C and gives the same results as

Prepending wildcards can slow your search down, but are sometimes useful

Example Search:
will find all _x_at probesets on the array.

4. Combining Search Terms with Logical Operators
You can combine terms in Standard Query searches by using the "&" (AND) "¦" (OR) and "!" (NOT) operators.
This will often give cleaner results than using wildcards between two terms.

Example Searches:
transcription factor & membrane
transcription factor & membrane & ! kinase
Non-Hodgkin's lymphoma & electron transport
