Abstract: The invention relates to a precursor for producing sintered metallic components, a method for producing the precursor and the production of the components. The object of the invention is to disclose possibilities of being able to produce sintered metallic components, which render possible an increased physical density and a reduced shrinkage on the fully sintered component. With a precursor according to the invention for the production of sintered metallic components, a coating layer is formed on a core, which is formed from respectively one particle of a first metallic powder. The coating layer is formed with a second powder and a binder. The first powder thereby has a particle size d90 of at least 50 ?m and the second powder has a particle size d90 of less than 25 ?m. The precursor is powdery.

Abstract: The invention relates to compounds comprising a plurality of enzyme substrates suitably linked and further carrying one or more cargo entities. In particular such compounds have the structure (substrate)n-linker-(cargo)m wherein “substrate” is a substrate specific for an enzyme-type protein; n is 2 or more; “linker” is a linking unit consisting of 1 to 300 atoms; “cargo” is a drug, a label detectable by a fluorescence detector, magnetic resonance imaging (MRI), positron emission tomography (PET) or scintigraphy, or a functional group which can be transformed into a drug or a detectable label; and m is 1 or more. The invention further relates to a corresponding molecular shuttles having the structure (fusion protein)n-linker-(cargo)m wherein “fusion protein” is a proteinaceous binding entity fused to an enzyme-type protein for which specific substrates exist. The proteinaceous binding entity is designed to bind to a target structure in vitro or in vivo, for example a cellular receptor.

Abstract: The invention relates to coenzyme A (CoA) type compounds carrying one or more drug entities and optionally a label detectable by a fluorescence detector, magnetic resonance imaging (MRI), positron emission tomography (PET) or scintigraphy, and/or a functional group which can be transformed into a drug or a detectable label. The invention further relates to a molecular shuttle which is a fusion protein comprising a proteinaceous binding entity directed to a target and an acyl carrier protein (ACP) or a fragment thereof, and carrying one or more drug entities. The proteinaceous binding entity is designed to bind to a target structure in vitro or in vivo, for example a cellular receptor.

Abstract: The present invention relates to methods of transferring a label from suitable substrates to O6-alkylguanine-DNA alkyltransferase (AGT) fusion proteins, to suitable fusion proteins, to suitable variants of AGT, and to novel labelled fusion proteins obtained. A protein of interest is incorporated into an AGT fusion protein, the AGT fusion protein is contacted with an AGT substrate carrying a label, and the AGT fusion protein is detected and/or manipulated using the label in a system designed for recognising and/or handling the label.

Abstract: The invention concerns a method for quantitative or qualitative determination of an analyte or its interaction or reaction kinetics in a system with at least two different phases, comprising the step of taking at least one measurement signal from at least one of the phases, whereby the different phases are present in parallel when taking the signal and whereby each measurement signal is attributed to one of at least two phases. In addition, the invention concerns a sample carrier, in particular for use in the method constituting the invention with one or more wells. The sample carrier is characterized by the fact that at least a portion of the sample carrier at least in the range of one or more wells is coated with fluorescence-quenching material.

Abstract: A device for carrying out and/or detecting affinity reactions comprises at least one surface or boundary surface on which an affinity reaction can take place, and at least one polymer bound to the surface. According to the invention, this device is obtainable by bonding the polymer to the surface in its pure phase, i e. essentially free of solvents. The polymer is preferably a terminally homo- or heterosubstituted bifunctional polymer, a corresponding polyalkylene glycol, in particular a polyethylene glycol, being preferred. The surface can be made of a metal oxide, in particular silicon dioxide. Before bonding the polymer, an activation of the surface, preferably by introducing functional groups by means of a silanization, can be effected.

Abstract: A process and a device are described for detecting physical, chemical, biological or biochemical reactions and interactions on biochemically or chemically functionalized specimen carriers in the form of layers or films from the spectral reflection after irradiation of the specimens with light of different wavelengths. In so doing, parameters for the nature of the specimens are determined in an economical and highly accurate manner and with a high degree of parallelism in the measurements. According to the process, the specimens are arranged on a substrate plate with a carrier layer of a carrier plate and are irradiated with light.
