Abstract: Herein is reported a method for producing an antibody comprising the steps of forming an antibody-antibody light chain affinity ligand complex, wherein the antibody light chain affinity ligand is immobilized on a solid phase, by applying a solution comprising the antibody to the immobilized antibody light chain affinity ligand, and incubating the complex formed in the previous step with one or more enzymes to modify the glycosylation of the antibody, thereby producing the antibody.

Abstract: A forging device for producing a piston blank has a forging mold that has an essentially cylindrical cavity matching the radial outer surface of the piston blank, a forging base delimiting the cavity, and a central die consisting of a mandrel that has a conically tapering extension which is mounted on the mandrel and the shape of which matches the inner surface of the piston blank. In order to form the radially outer surfaces of the piston slipper walls and a peripheral cooling pocket located radially outside the slipper walls in the piston head, the forging device has two lateral jaws which are mounted in the forging device so as to be movable at an angle to the longitudinal axis of the forging device.
