1. "The chief drawback of genetic sequencing is the huge cost involved. It requires a genetic sequencer and supercomputer, the combined value of which can be £4 million. However, a Chinese company recently agreed to loan Pitsiladis a sequencer and he has secured funding recently of about £750,000 from Wada, the International Olympic Committee and other sponsors. If additional funding is secured, he is hopeful of having the test in place for the Tokyo Olympics next year. That might be too soon for genetic sequencing to become a sanctionable Wada test, but it could at least provide anti-doping investigators with intelligence."
The supercomputer part of this is pure journalistic BS. The data analysis they use will run on any decent desktop computer. For the sequencing part, you do not typically buy these machines, AFAIK. You rent time on them. Still, full testing of the Olympic Games is a ton of tests, so big bucks.
2. "I wonder who they experimented this one on?"
Quote from their paper: "The blood transcriptional signature of recombinant human erythropoietin administration and implications for anti-doping strategies":
"In a proof-of-principle study, we identified, replicated and validated the whole-blood transcriptional signature of rHuEPO in endurance-trained Caucasian males at sea-level (n = 18) and Kenyan endurance runners at moderate altitude (n = 20), all of whom received rHuEPO injections for four weeks."
