Other technologies should be considered for the profi ling of focused sets of genes. Nanostring technology can, for instance, detect the abundance of up to 500 transcripts with high sensitivity [19] . Th e approach is 'digital' since it counts individual RNA molecules using strings of fl uorochromes as reporters to identify the diff erent RNA species. Other technology platforms developed by, among others, Luminex, High Th roughput Genomics or Fluidigm round up the off ering for 'subgenome' transcript profi ling.
