Are you hinting that GTCB is having a problem ramping up enough ATRYN? Ya know, I don't recall ever hearing how well the process of purifying ATRYN has been going. Could there be a problem???

Re: Downstream processing of ATryn

The Cambrex operation relevant to GTC was acquired by Lonza last year (#msg-14249326, also #msg-14736913 about one-fourth of the way down). Lonza is the clear number-one company in the contract-manufacturing business and GTC has had a good, working relationship with Lonza for many years. In short, I see no problem whatsoever in this aspect of the business. Regards, Dew
