description: The Monsanto Arabidopsis Genome Array is a custom array designed using Affymetrix GeneChip CustomExpress Array Design Guidelines.  Feature size is 18 micron; and there are 9 probe pairs per transcript randomly distributed across the array. The sequences used for probe selections are mostly based on gene models released by TIGR in 2001. Additional gene models from Monsanto EST collections were also used. Probe sets have been mapped to TAIR AGI identifiers whenever possible.  There are 27,385 probe sets on the array, which consists of perfect match and mismatch probe pairs.  Standard Affymetrix controls have been used on the chip along with control made from internal sequences.
