Gene-specific cross-species hybridization on our multi-species array. Example of a representative result for average log signal intensities is shown for all the 3,456 transcripts on the array. The red dotted line represents background intensity. The three candidate genes and our positive control GAPD are identified. Note that Spin transcript is present 3 times on the multi-species microarray. Smfn; Small fragment nuclease, Spin; Spindlin, Prmt1; Protein arginine methyltransferase 1.
