The GeneChip™ Rat Genome 230 2.0 Array is a powerful tool for toxicology, neurobiology, and other applications using rat as a model organism.

• Provides comprehensive coverage of the transcribed rat genome on a single array
• Comprised of more than 31,000 probe sets, analyzing over 30,000 transcripts and variants from over 28,000 well-substantiated rat genes
• Sophisticated bioinformatics tools available through the NetAffx™ Analysis Center to rapidly obtain biologically meaningful results
• Publicly available drafts of the rat genome and leading public rat databases were used to refine sequences and provide a higher quality of data output

Array Profile
All probe sets represented on the GeneChip Rat Expression Set 230 are included on the GeneChip Rat Genome 230 2.0 Array. Sequences used in the design of the GeneChip Rat Genome 230 2.0 Array were selected from GenBank™, dbEST, and RefSeq. The sequence clusters were created from the UniGene database (Build 99, June 2002) and then refined by analysis and comparison with the publicly available draft assembly of the rat genome from the Baylor College of Medicine Human Genome Sequencing Center (June 2002).

The GeneChip Rat Genome 230 2.0 Array includes representation of the RefSeq database sequences and probe sets related to sequences and refined EST clusters previously represented on the GeneChip Rat Genome U34 Set.

Oligonucleotide probes complementary to each corresponding sequence are synthesized in situ on the arrays. Eleven pairs of oligonucleotide probes are used to measure the level of transcription of each sequence represented on the GeneChip Rat Genome 230 2.0 Array.

Frequently asked questions (FAQs)

What reagent kit should I use with my array?

Please refer to the Microarray Reagent Guide for Arrays and Expression Kits to match the correct reagents your array.

How are transcript IDs assigned for WT arrays if a gene has multiple transcript IDs?

The first assigned mRNA/gene that is listed in the annotation file for a given probe set or transcript cluster is considered the "best" assignment based on data source quality ranking and assignment scoring system. To get a single best mRNA/gene assignment you can simply take the first one in the list in the annotation file.

Sometimes, there might be multiple best hits between transcript clusters (or probe set) and a mRNA/gene, with identical score and data source quality. In that case, the transcript assignments are ranked based on their descriptions (e.g., title from the GenBank record).

For transcript clusters that detect genes that are alternatively spliced, the different spliced forms will be ranked by length with the longest ones listed first.

Does the GeneChip miRNA 3.1 Array Strip require a different hyb/wash/stain kit than the GeneChip 3' IVT arrays and GeneChip ST array strips?

The hyb/wash/stain kit for the GeneChip miRNA 3.1 Array Strips is different than that for the 3' IVT arrays and GeneChip ST array strips. Additional wash A steps have been added to ensure adequate washing after the array strips have been stained.

What do the suffixes mean at the end of each probeset in GeneChip 3' IVT arrays?

The probe set names never change, but they can give you an idea of what was known about the sequence at the time of design.
_at: All probes hit one known transcript.
_a: All probes in the set hit alternate transcripts from the same gene.
_s: All probes in the set hit transcripts from different genes.
_x: Some probes hit transcripts from different genes.

Can I store my GeneChip 3' IVT Array after hybridization?

Yes, but we recommend storing your GeneChip 3' IVT Array after hybridization and prior to the fluidics step, for no longer than 3 hours at 4 degrees C. Please remove the hybridization cocktail and fill with wash A before storing.
