Abstract: The present invention relates to a bispecific single chain antibody molecule comprising a first binding domain consisting of one antibody variable domain capable of binding to an epitope of the human and non-chimpanzee primate CD3 epsilon chain, wherein the epitope is part of an amino acid sequence comprised in the group consisting of SEQ ID NOs. 2, 4, 6, and 8, and a second binding domain capable of binding to an epitope of a human and a non-chimpanzee primate tumor target antigen. The invention further relates to a bispecific single chain antibody molecule comprising a first binding domain capable of binding to an epitope of human and non-chimpanzee primate CD3? (epsilon) chain, wherein the epitope is part of an amino acid sequence comprised in the group consisting of SEQ ID NOs. 2, 4, 6, and 8, and a second binding domain consisting of one antibody variable domain capable of binding to an epitope of a human and a non-chimpanzee primate tumor target antigen.

Abstract: A power supply for an x-ray emitter is disclosed. A voltage source of the power supply is configured to provide an acceleration voltage or a heating voltage between a first internal contact and a second internal contact to, in a first operating mode, supply the x-ray emitter with power. The power supply includes a control device configured, in a second operating mode, to detect a voltage between the first and the second internal contact and/or to detect a current via the first and/or second internal contact. As a function of the detected voltage and/or of the detected current, the control device is configured to activate a warning device for giving a warning and/or to transmit a warning signal. A method is further disclosed.
