Abstract: The present invention provides a novel antibody-RNase conjugate which is a single chain protein, providing both the specificity of its antibody portion and the RNase activity of its RNase portion, resulting in an antigen specific effectiveness against cells when applied in vivo or in vitro, wherein the RNase portion is effectively cytotoxic in at least a fraction of cells presenting the antigen, e.g. after internalization by endocytosis. In detail, the present invention provides scAb-RNase conjugate having the principal structure of scFvFc-RNase. This structure could also be shown to allow the effective production of antigen-specific and cytotoxic conjugate protein in cell culture, the conjugate having a high activity with respect to antigen specificity and cyto toxicity.

Abstract: The present invention refers to synthetic antibody molecules which comprise domains from naturally occuring antibodies, e.g. domains derivable from IgG, preferably of human origin, in a novel arrangement. Single chain molecules are provided which are suitable for expression in micro-organisms in their active conformation, which single chain molecules generally comprise a VL domain, a CL domain, and a VH domain, a CH1 domain, linked by a linker arranged between VUCL and VH/CH1. Accordingly, these antibody molecules can be termed single chain Fabs (scFabs). These antibody molecules are single chain proteins, which can also be associated to dimers, including heteromeric antibodies, wherein at least two single chain antibody molecules are associated.

Abstract: The invention relates to a method for highly parallel production of complex molecule libraries on the surface of a substrate with the aid of regeneratable matrix dies. According to prior art, the production of molecule libraries on a support is expensive, and requires a lot of time and a large amount of apparatus. By using regeneratable matrix dies it is possible to simplify and accelerate the production of molecule libraries, especially DNA and protein libraries, in a significant manner. The matrix-10 die is made of an elastic material such as polydimethylsiloxane and includes locally-bound matrix molecules on the surface thereof, said molecules being used as a model for the synthesis of copy molecules. The copy molcules are transferred to the target surface by means of a contact printing method. The matrix molecules remain on the die for further synthesis and print cycles which can repeated several times. The inventive method is suitable for copying and reproducing differently produced molecule arrays.

Abstract: A phagemid has been constructed that expresses an antibody fused to coliphage pIII protein. The phagemid is suitable for selecting specific antibodies from large gene libraries with small quantities of antigen. The antibody-pIII gene can be strongly repressed, so that it allows antibody libraries to be amplified without the danger of deletion mutants predominating. After induction, large quantities of the fusion protein may be expressed.

Abstract: According to the method for detecting optical properties, especially luminescence reactions and refraction behavior of molecules which are directly or indirectly bound on a support, electromagnetic waves, especially laser light, are radiated onto the support. The light that is emitted or refracted by the molecules is then detected by a detector. The detector and the support are moved in relation to each other during and after the radiation of the electromagnetic waves. The support used is especially a transparent support with integrated position markings which can be detected by a detector, especially an optoelectronic scanning system. At least one of the integrated position markings is selected while the support and the detector are being moved in relation to each other or thereafter so that the light that is detected by the detector can be associated with a location on the support.
