GeneChip® Rat Exon 1.0 ST Arrayは、エクソンあたりのプローブ数が約4個、遺伝子あたりのプローブ数が約40個のアレイで、遺伝子発現と選択的スプライシングという2つのレベルの相補的な解析を可能にします。
各エクソンに複数のプローブを採用したことで、「エクソンレベル」の解析を実現し、1個の遺伝子の異なるアイソフォームを識別することが可能です。このエクソンレベルの解析を全ゲノム規模で行うことで、疾患メカニズムや病因において中心的役割を担うと考えられる、エクソン使用についての特定の変化を検出する扉が開かれます。
もう一つの「遺伝子レベル」の発現解析では、異なるエクソンにある複数のプローブのデータを、同じ遺伝子に由来するすべての転写産物の発現値にまとめます。
エクソンアレイは、実験的な証拠のある転写配列や予測される転写配列など、ゲノムを最も包括的にカバーしたアレイで、これまで同定されていない新規転写産物の発見を可能にします。
この統合されたソリューションの特長として、以下が挙げられます。
- 超高解像度の発現解析によって、ゲノム全体の既知転写領域と予測される転写領域内にある850,000個以上のエクソンクラスターを解析(さらに詳しくはこちら)
- 転写産物の全長にわたってセンス鎖ターゲットを生成するランダムプライミング法を採用した、独自のGeneChip® Whole Transcript(WT)Assayと試薬キット(さらに詳しくはこちら)
- ユーザ独自のさまざまなワークフローでデータを探索、解析する機会を提供する、柔軟性のあるデータ解析ソリューションと包括的なアノテーション

| マウスまたはラットmRNAによるサポート | 272,061 プローブセット |
| 遺伝子予測によるサポート | 875,666 プローブセット |
| プローブ選択領域 | 転写産物の全長 |
| プローブ/プローブ選択領域 | 4¹ |
| バックグラウンド補正方法 | 同じGC含量をもつ1,000のバックグラウンドプローブの中央値強度 |
| アレイあたりのプローブセル総数 | 約4,000,000 |
| ターゲットの方向性 | センス鎖2 |
| 1プローブ選択領域の長さと配列上の制約のため、約10パーセントのエクソンプローブセットではプローブが4未満となっています。 2アレイ上にタイリングされているプローブはアンチセンスの方向でデザインされているため、センス鎖標識ターゲットをアレイにハイブリダイズさせる必要があります。本アレイはセンスターゲットを用いる必要性(標識サンプルがアレイにハイブリダイズされる)から、STアレイと呼ばれています。 |

Alignment, Annotation, and Sequence Files
Information about using Alignment, Annotation, and Sequence files
IGB Annotation Files
RaEx_1_0-st-v2 Annotations, Rn3/Build 3.1, BGN
Note: The IGB BGN annotation files can be used to load up transcript cluster, probeset, and probe level annotations for the Affymetrix GeneChip® Arrays into IGB. These files allow the user to quickly load a whole chromosome of annotations. For visualizing smaller genic regions the NetAffx IGB links should be used.

RaEx-1_0-st-v1 Transcript Cluster ID Mappings to Rat 230 (168 KB, 8/28/06)
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.
