I've found the company on the internet. Tried to send them a fax - the fax couldn't connect... Tried to call them - got an answering machine that didn't state the company name, but simply said "the person you're calling is not available..."
Something's stinks here...
I'll contact the newspaper and inform them about this and my information on the identity of PC-1 as an already known general cancer marker and not a prostate specific one! ...This has me spooked...
