first human genome = ten years @ $1 billion
The quest for the $1K human genome
2nd: 10,000 instrument days (30 instruments for 1 year) @ $10 million
J. Craig Venter3rd: 454 pyrosequencing, two months @ $2 million
James Watson
Nature, Nov 2008 -- “effectively” 4 human genomes (@$100K each)- first African genome (Illumina, UK)- first Asian genome (Beijing Genomics, China)- first cancer genome (Washington University, USA)
The $1,000 human genome, coming soon?
