Abstract: Described are compositions, in particular lyophilizates, containing proteolytic enzymes, and methods for producing the compositions. Typically these compositions contain one or more proteases with collagenase activity and a neutral protease, for example, thermolysin. The compositions are free of acetate salts. Surprisingly, such compositions can be dissolved in water more rapidly than lyophilized protease mixtures of the state of the art.

Abstract: A method and cartridge for determining an amount of at least two analytes in a biological sample and an automatic analyzer are disclosed. The cartridge may comprise a cartridge inlet, a sample holding chamber fluidically connected to the inlet, and two or more metering chambers. Each metering chamber may comprise a sample inlet, a sample outlet, and a metered outlet for dispensing a predetermined volume. At least one sample distribution channel is connected between the sample outlet of a metering chamber with a sample inlet of another metering chamber. For each metering chamber, a connecting tube fluidically connects the sample inlet with the sample holding chamber, a microfluidic structure for processing the sample into a processed sample connects to the sample outlet, and a measurement structure fluidically connects to the microfluidic structure and enables measurement of the processed sample to determine the amount of the analyte in the processed sample.

Abstract: A method to handle tubes in a diagnostic laboratory automation system comprising a control device and a tube-analyzing device is presented. The tube-analyzing device comprises a tube identification reader, a tube type recognition unit, a sample color determination unit, and a tube consistence unit. The tube identification reader reads tube identification device. The tube type recognition unit identifies tube type. The sample color determination unit determines sample color. The tube consistence unit determines sample consistency. The sample tube type, the tube type, the sample color, the sample consistency are send to the control device. The control device determines a construed tube type from one or more of the information of the tube type, the sample color, and the sample consistency. The control device checks whether the tube type matches the construed tube type and changes a used tube type from the tube type to the construed tube type.

Abstract: Disclosed is a simplified process for producing magnetic polymer particles. The process comprises: (a) providing a composition having a liquid monomer which is radical polymerizable, a radical initiator soluble in the monomer, a steric stabilizer, and a ferrofluid comprising surfactant-coated colloidal magnetic particles in a carrier fluid which is miscible with the monomer; (b) preparing an emulsion from a polar solvent which is immiscible with the monomer, and the composition of step (a); (c) adding seed polymer particles to the emulsion, mixing to form a seeded emulsion, and incubating the seeded emulsion, thereby swelling the seed polymer particles; and (d) activating the radical initiator and polymerizing the monomer in the swollen seed polymer particles; thereby producing the magnetic polymer particles. The process forms monodisperse magnetic particles. The particles are characterized by a uniform distribution of magnetic material, and an absence of magnetite bleeding.

Abstract: An automatic analyzer cartridge, spinnable about a rotational axis, has fluid and aliquoting chambers, a metering chamber connected to a vent that is nearer to the rotational axis than the metering chamber, first and second ducts connecting the fluid and aliquoting chambers, and the metering and aliquoting chambers, respectively. Metering chamber side walls taper away from a central region, wherein capillary action next to the walls is greater than in the central region. Fluid flows to the metering chamber using capillary action via the second duct that has an entrance and exit in the aliquoting and metering chambers, respectively; the exit being closer to the rotational axis than the entrance. A downstream fluidic element connects to the metering chamber via a valve. A fluidic structure receives and processes a biological sample into the processed biological sample and has a measurement structure that enables measurement of the processed biological sample.

Abstract: The present invention relates to a monoclonal antibody capable of binding to biotin. In one embodiment the monoclonal antibody according to the invention also does not bind to a biotin moiety on a biotinylated molecule, wherein the biotin moiety is attached to the molecule via the carbon atom of the carboxyl function of the valeric acid moiety of biotin. Also disclosed is a method for generation of an antibody as disclosed herein. The monoclonal antibody according to the invention is of specific use in a method for measuring an analyte in a sample, wherein a (strept)avidin/biotin pair is used to bind a biotinylated analyte specific binding agent to a (strept)avidin coated solid phase.
