Abstract: The present invention relates to a method for purifying proteins, which proteins are produced by homologous or heterologous expression in a ciliate host, from harvested cell culture fluid (HCCF) which was not chromatographically purified. The method comprises the steps of incubating a harvested cell culture fluid with a kosmotropic agent, efflorescing protein by formation of crystals, and, optionally, harvesting effloresced protein.

Abstract: A method for operating a motor vehicle door, according to which method the motor vehicle door is equipped, for example, with an actuator and/or a motor vehicle door lock in the form of a current consumer, and at least one sensor for detecting door movements. In addition, a control unit that evaluates signals from the sensor is provided which can be transferred from a rest mode into an operating mode and back again according to the recorded door movements. According to the invention, the door movement causes the sensor that is deenergised in the rest mode to generate a current pulse.

Abstract: A method for preparing for the start-up of a control unit for access devices, wherein at least one access device is communicatively connected to the control unit, wherein the control unit has a communication interface for information technology communication with a mobile terminal and/or has an input device for detecting an input from an installer or is in communicative connection with an input device for detecting an input from an installer. The method includes: a) detecting, using the control unit, an information technology signal or a change in an existing information technology continuous signal of a mobile terminal by the communication interface, and/or detecting an input from an installer using the input device, b) sending a trigger signal from the control unit to the access device, c) receiving the trigger signal using the access device, and d) performing an action using the access device depending on the received trigger signal.

Abstract: A method for commissioning a door system with the door system having door components, with at least one door component being designed as a control unit, with the method including the following steps: storing an electronic configuration of the door system in the control unit and/or a mobile terminal, and carrying out at least one commissioning step by the electronic configuration.
