Abstract: The present disclosure relates to methods of sanitizing a chromatography medium. The present disclosure also relates to regenerating the chromatography medium.

Abstract: The present disclosure relates to methods of purifying immunoglobulin G (IgG) and other proteins, such as albumin, from plasma or a fraction thereof using an affinity chromatography resin comprising a ligand capable of specifically binding to a CH3 domain of human IgG. The present disclosure also relates to formulation and uses of plasma protein product produced from the method.

Abstract: A fuel cell device is provided comprising a fuel cell stack, which is formed from a plurality of unit cells which are stacked one above the other in a stacking direction and which each have one or more media channels and a membrane electrode assembly, which comprises a cathode, an anode and a membrane arranged between the cathode and the anode, as well as comprising a media guide extending essentially in parallel to the stacking direction. The media guide can be or is connected to the fuel cell stack in such a way as to guide a medium essentially laterally to the stacking direction into or out of the media channels of the unit cells of the fuel cell stack.

Abstract: The present invention relates to an assembled shaft element, in particular an assembled camshaft for valve-controlled internal combustion engines, wherein a hub body having at least one functional part, in particular at least one cam, is held on a shaft by a formfit connection using a splined tooth system in the circumferential direction, wherein the splined tooth system includes shaft splines formed on the shaft and interacting with hub body splines formed in a hub body recess. According to the invention, the at least one hub body (14) is held in addition to the circumferential formfit connection by an interference fit on the shaft (12) implemented by a press fit between a tooth circle of the shaft splines (22) and a root circle of the hub body splines (26). The invention further relates to a method for producing an assembled camshaft for valve-controlled internal combustion engines.
