The following microarray comparison analysis spreadsheets are designed to help expression analysis customers compare and understand the relationship between the data generated using related GeneChip™ Arrays.

As sequence databases evolve, we periodically update our expression products to ensure that you have the greatest and most accurate genome coverage possible. In addition, as advances are made in the technology for designing and making these products, we pass on these improvements with product updates. These changes often mean that particular sequences or clusters are represented differently between versions of a product. The microarray comparisons are available for both same species and cross species, as listed below.
