The holy grail for lowering the cost of DNA sequencing is to build a machine that can sequence an entire individual human genome for $1,000. That price-point is perhaps the point at which routinely decoding the full genome as part of an individual’s basic medical data becomes attractive. That achievement is still quite a ways away, but here’s an article that discusses "second generation" DNA sequencers now hitting the market that are making real progress toward the one-grand genome. One thing’s for sure, when the price drops drastically (the first genome sequence cost @$500 million) the rate of use tends to go up inversely. Genes, genes everywhere.
