GeneChip^® Mouse Exon 1.0 ST Array

With approximately four probes per exon and roughly 40 probes per gene, the GeneChip® Mouse Exon 1.0 ST Array enables two complementary levels of analysis—gene expression and alternative splicing.

Multiple probes per exon enable "exon-level" analysis and allow you to distinguish between different isoforms of a gene. This exon-level analysis on a whole-genome scale opens the door to detecting specific alterations in exon usage that may play a central role in disease mechanism and etiology.

The second level is "gene-level" expression analysis, in which multiple probes on different exons are summarized into an expression value of all transcripts from the same gene.

Exon arrays provide the most comprehensive coverage of the genome, including empirically supported and predicted transcribed sequences, enabling the discovery of previously unidentified novel events.

Array Features

Highest resolution expression analysis, interrogating over 1 million exon clusters within the known and predicted transcribed regions of the entire genome.

¹ About 10 percent of the exon probe sets have fewer than four probes due to the probe selection region length and sequence constraints. ² The probes tiled on the array are designed in the anti-sense orientation, requiring sense-strand labeled targets to be hybridized to the array. By convention, the array is called ST array representing the necessity of using sense targets (the labeled samples to be hybridized to the array).

Note: For gene level analysis you will need to download one of the probeset level annotation zip files (CSV) to get the meta-probeset lists. None of these files contain textual biological annotations such as gene name or GO annotations; textual biological information can be found in the NetAffx Transcript CSV file. The design time Probeset CSV file provides information about the probeset such as genome coordinate and supporting annotation types. This is a subset of information found in the NetAffx Probeset CSV file. The Probeset CSV file is also a subset of the Full GFF files which contain transcript cluster, exon cluster, probeset, and probe level annotations. The GFF files also contain information about the specific annotations supporting each of the probesets. For example, use the Full GFF files for pulling design time information into a local database. The Mappings TSV file contains mappings between other arrays and annotations.

The transcript cluster mapping files provide gene level mappings between 3' IVT probesets and exon array transcript cluster IDs.

Note: NetAffx annotation files are intended for use in automated analysis. Some are not compatible with all spreadsheet applications. Please use the NetAffx Analysis Center to limit download data to your probe sets of interest. Annotation CSV files for the exon arrays are split into a probe set-level annotation file and a transcript cluster-level annotation file; exon array CSV files are compatible with ExACT.
