What is a SNP probe search?

A SNP probe search returns Agilent SNP probes from the eArray probe database. Agilent SNP probes are a special subset of the probes that are available for the CGH application type. In all types of SNP probe searches in eArray, you enter search parameters, and submit a search job. When eArray finishes the search job, the search results become available in your individual or collaboration workspace. You can then create a probe group with the returned probes and use the probe group in a CGH+SNP microarray design.

The SNP probes that are available in eArray are designed specifically for use on the Agilent CGH+SNP platform. This platform combines both CGH and SNP probes on the same microarray, and lets you detect copy-neutral variations such as UPD (uniparental disomy) and cnLOH (copy-neutral loss (or lack) of heterozygosity). For more information, see CGH+SNP microarrays.

These types of SNP probe searches are available:

Entire Agilent SNP Probe Set Search – Returns Agilent SNP probes from across the genome.
Genomic Interval Search – Returns Agilent SNP probes that map to genomic intervals that you enter or upload.
Probe ID Search – Returns Agilent SNP probes that have the specific probe IDs that you enter or upload.
SNP ID Search – Returns Agilent SNP probes that correspond to SNP IDs that you enter or upload.
