            <dt> Probesets from the <a href="http://www.affymetrix.com/" target="_new">Affymetrix</a> GeneChip <i>Drosophila</i> Genome 1.0 and 2.0 Arrays, a
             microarray tool for studying expression of <i>D. melanogaster</i> transcripts. Probeset locations and mapped genes (not transcripts) are downloaded from Ensembl. FlyMine only loads probesets that match to at least one gene.
