...They had expected -- or at least hoped -- to see a shift in the colorof light once the RNA was mixed in. Instead, they saw two shifts in thecolor given off. First, there was a slight shift, indicating a smallchange in the distance between eIF1 and its relative, and then a muchlarger shift, indicating a muc...New Study from Affymetrix Laboratories Points to Changing View of How Genome Works
... Tiling Arrays: Affymetrix "tiling" arrays mark a shift in the way microarrays are designed and interpreted. By using a neutral approach to array design, tiling arrays include all non-repetitive sequence from a given genome, not just the hand-selected regions that were previously thought to be important. ...Affymetrix and the Karolinska Institutet Announce Translational Medicine Strategic Alliance
