The GeneChip® Human Mapping 250K Nsp Array is a subset of the GeneChip® Human Mapping 500K Array Set. This lower-density, cost-effective solution enables screening of the entire genome for gross abnormalities. The array has probes for genotyping 262,000 SNPs and each marker can be interrogated with up to five probes, ensuring cross-verification for data integrity.
The Human Mapping 250K Nsp Array has the most extensive publication database compared to other similar arrays. Researchers have published cytogenetic studies for blood and solid tumor cancers.
