Abstract: The invention relates to novel bispecific antigen binding molecules, comprising at least two antigen binding domains capable of specific binding to OX40 and a particular antigen binding domain capable of specific binding to Fibroblast Activation Protein (FAP), and to methods of producing these molecules and to methods of using the same.

Abstract: The invention relates in one variant to a suction pump (1) for sucking body fluid, comprising an optical status indicator (5) for displaying a light signal as a function of the operating state of the suction pump (1), the optical status indicator (5) is arranged on at least two points of the outer surface of the suction pump (1), the surface normals of which are at an angle of at least 5° to one another. In a second variant, the invention relates to a suction pump (1) for sucking body fluid, including an optical status indicator (5) for displaying a light signal as a function of the operating state of the suction pump (1), wherein the suction pump (1) has on its underside at least one stand (13) for support on a support surface, the status indicator (5) is arranged on the underside of the suction pump (1) so that the light signal is emitted in the direction of the support surface.
