..., with a few additions from the microRNA registry, the Mammalian Gene Collection (MGC), and Ensembl ( Gerhard et al. 2004 ; Griffiths-Jones 2004 ; Birney et al. 2006 ). For each promoter,
there is an average of 4 probes of 45–60 nucleotides each tiling ∼1000 bp upstream and 300 bp downstream. We hybridized...
