== (a): Comparison of productivities of your Fc-fusion proteins after transient transfection. of your automated system (ViCell, Beckman Coulter). Meant for transient appearance plasmid DNA and polyethylenimine "Max" (Polysciences, Eppelheim, Germany) were diluted into OptiMEM medium (Life Technologies) and added to the cells after complex development. The titer of the unit protein in the supernatant was measured simply by Protein A HPLC upon day 4 and time 6 post transfection. Cellular material were stably transfected simply by electroporation (Amaxa Nucleofection system, Lonza, Germany) with an expression plasmid development for a man monoclonal antibody according to the manufacturer's instructions. forty eight…
