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: The present invention relates to prefabricated microparticles for performing a specific detection of one or several analytes in a sample, and to precursors of such microparticles, herein also sometimes referred to as “precursor-microparticles”. In particular, the present invention relates to libraries of such prefabricated microparticles and libraries of such precursor-microparticles. Furthermore, the present invention relates to kits for making such libraries and to kits of using such libraries for detecting an analyte of interest in a sample. Moreover, the present invention relates to methods of detecting and/or quantitating an analyte of interest in an aqueous sample, preferably using such kits.
