Hi all, If anybody is interested in non-viral stable expression, we have a piggybac-based, doxycycline-inducible system. It is the reference 40 in the lentiviral paper that Tomas directed to. We’d be happy to distribute the plasmids. Zhijie > On Jan 25, 2020, at 3:26 AM, Tomas Malinauskas

Hello CCP4-ers, I was wondering what people have found to be the best human cell line expression system for making a large quantity of purified recombinant protein. Any information and protocols would be greatly appreciated. Happy 2020, Gloria
