Figure 1From: Identification and utilization of inter-species conserved (ISC) probesets on Affymetrix human GeneChip® platforms for the optimization of the assessment of expression patterns in non human primate (NHP) samplesAlgorithm for identifying ISC probesets in Affymetrix Human GeneChip® platforms. In the Affymetrix platform, a probe is a 25-mer oligo. A set of 11–20 probes forms a probeset. An ISC probeset is defined as having at least two probes that are complementary to ESTs in NHP. A perfect probeset is the one that all of its probes are complementary to ESTs in NHP.Back to article page
