With approximately four probes per exon and roughly 40 probes per gene, the GeneChip® Rat 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 850,000 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).
