Proven performance from the industry standard
The GeneChip® PrimeView Human Gene Expression Array cartridge enables expression profiling using probe sets with an emphasis on established, well-annotated content. Sequences used in the design of the array were selected from the UniGene database 219, RefSeq version 36, and full-length human mRNAs from GenBank®.
The PrimeView Human Gene Expression Array enables you to:
- Measure gene expression of more than 36,000 transcripts and variants per sample
- Get accurate and reproducible gene expression data by using multiple independent measurements for each transcript
- Offers excellent gene expression accuracy and reproducibility
- Multiple independent measurements per transcript for increased confidence in your results—11 probes per set for well-annotated sequences, 9 probes per set for the remainder
- Provides complete coverage of the annotated genome
- The PrimeView Human Gene Expression Array is comprised of more than 530,000 probes covering more than 36,000 transcripts and variants, which represent more than 20,000 genes mapped through UniGene or via RefSeq annotation.
- The EST and mRNA sequences used in the design were clustered and assembled to create consensus sequences that represent alternative splice forms. Each assembly was then analyzed for orientation and alternative 3' end evidence.
- Content was chosen to cover all well-annotated genes and transcripts from RefSeq v36 and by leveraging all available EST and mRNA evidence that fall into the same clusters, to rigorously detect alternate 3' ends of those well-annotated genes.
- More than 1,000 probe sets represent transcripts that have no official gene symbol in UniGene, but are based on predicted RefSeq sequences and UniGene clusters with good evidence of actual transcription.

Alignment, Annotation, and Sequence Files
Current NetAffx Annotation Files
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.
