Abstract: The invention relates to a method for producing polyclonal antibodies against an antigenic target protein which comprises inducing an immune response in a host by applying an immunogenic composition comprising membrane vesicles incorporating said antigenic target protein to said host and obtaining antibodies against said target protein from the host's serum.

Abstract: The invention relates to an improved cell-free protein synthesis method using a eukaryotic cell lysate in the presence of a caspase inhibitor, to a device for carrying out said method, and to the use of a caspase inhibitor for increasing the protein yield or for increasing the stability of the synthesized proteins in such a cell-free protein synthesis method using a eukaryotic cell lysate. In a preferred embodiment of the invention, the cell-free protein synthesis method is carried out as a continuous method in a device which comprises at least two compartments separated by a dialysis membrane. The translation reaction takes place in at least one first compartment, the reaction compartment, and during the translation reaction i) reactants are diffused from at least one other compartment, the supply and discharge compartment, into the reaction compartment, and ii) reaction byproducts are diffused from the reaction compartment into the supply and discharge compartment by means of the dialysis membrane.
