Once they know the structures, they may not only be able to provide new details on how anthrax develops, but also pick out structural vulnerabilities that are key to designing new therapeutic agents to prevent a...

New Study from Affymetrix Laboratories Points to Changing View of How Genome Works

...ed 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. With the inclusion of all genomic sequences, microarrays can now be used as a discovery to...
