Just yesterday, one of those Fools, All-Star zzlangerhans, succinctly summed up the Repligen bull case for our community:

I missed the bump in Repligen's share price in the spring because I set an outperform threshold of 6 that never quite clicked. The stock has been pulling back over the last month but I still like the growing bioprocessing revenues, courtesy of the excellent acquisition of Novozymes Biopharma Sweden AB in 2011. Repligen still has to outgrow a well-deserved reputation for futility but if they can successfully transition from drug development into products and services there's still a lot of potential for share price appreciation.
