>GTC methods aren't cheap when you factor in having to get approved on a new method of production<<
Just to elaborate, I thought bio-reactors cost as much as 600mil and that GTC's cost 60mil, leaving a lot of margin for "issues" with respect to the novel platform. Also, GTC's is expandable from its established base. For example, re. AAT, I think they already have the manufacturing marked out with high yield. I am naive, but it seems perfect to me.
Not picking a fight, genuinely interested in learning - thanks.
