The NCGR Sequencing Center last week celebrated completion of its 1000th Illumina sequencing flowcell. This brings the total number of raw bases produced by the Center since its inception to over 3 Trillion.  Hats off to to the small but dedicated and brilliant Sequencing Center staff!  Ironically, the 1000th flowcell was actually done on our one remaining Illumina GAIIx machine, which was also the first workhorse installed in the Center six years ago.
