Probe sequences are selected from either a consensus or an exemplar sequence derived from the Affymetrix sub-clusters. The following table lists Affymetrix' array designs that involved sub-clustering, and includes the consensus/exemplar information:
| ArrayName | Consensus/Exemplar design? |
| HG-U133 | Consensus and Exemplar |
| HG-U95 | Consensus |
| HuGeneFL | Exemplar |
| MG-U74 | Consensus |
| Mu19K | Consensus |
| RG-U34,RT-U34,RN-U34 | Exemplar |
