The annotation and sequence files contain the complete entries for all probe sets on the array, taken from the NetAffx Analysis Center. They are intended to be used primarily in spreadsheet applications and database programs (such as SQL databases). Interactive and Batch queries can be performed in the NetAffx Analysis Center to find information for individual probe sets of interest.

Annotation files are available for most Affymetrix GeneChip® Arrays. They are listed with other available support material on the Support by Product page. Please select your array of interest.
