GeneChip® Universal Tag Arrays are available in 3K, 5K, 10k or 25K configurations and contain novel, bioinformatically designed tag sequences that result in minimal potential for cross-hybridization.

Due to the universal nature of the tags, custom SNP assays do not require redesign or creation of custom arrays.
