Abstract: The present invention pertains to a device for separating plasma from a blood sample comprising a stacked structure which is provided with a first portion including a separating member having a first surface for applying or receiving the blood sample, wherein the separating member is adapted to permit the passage of plasma but to inhibit the passage of cells, and a second portion including an absorptive member for absorbing the plasma, which has a second surface in contact with the separating member for receiving the plasma, wherein the absorptive member is adapted to generate a capillary pressure so as to draw plasma from the separating member to the absorptive member. The first portion is fixed to the backing member in a manner to be removed without destroying the absorptive member. The absorptive member is fixed to the backing member in a manner to be removed without destroying the absorptive member.

Abstract: This invention provides compositions and methods for HCV typing, e.g., genotyping and/or subtyping. The compositions and methods of the invention can be used to assign an HCV isolate to one of at least five HCV types (for example, selected from types 1, 2, 3, 4, 5 or 6), or to one of at least five subtypes (for example, subtypes 1a/b/c, 2a/c, 2b, 3a, 4a, 5a or 6a). These methods integrate the hybridization data from a plurality of HCV typing probes in a multidimensional analysis to make an HCV type assignment for an HCV in an experimental sample. The invention also provides related compositions, including, for example, the HCV typing probes and HCV typing diagnostic kits.
Abstract: The invention is a method of amplifying nucleic acids by synthesizing an engineered amplicon containing the sequence of interest, but omitting intervening sequences present in the template molecule. The method utilizes an “amplicon bridge” incorporated into the amplification primers. The length and content of the desired amplicon can be chosen by the operator and can contain unique regions for probe binding.
Abstract: A method for mounting and combination of an analytical apparatus with a platform for mounting such an apparatus comprising at least two units, and a platform on which said apparatus is mounted is disclosed, said platform comprising at least one platform element, and multiple feet for placing the platform elements on a surface. The feet are individually adjustable in height.

Abstract: The present invention relates to methods and reagents for modifying the emission of light from labeled nucleic acids for the purpose of real time detection, analysis, and quantitation of nucleic acid sequences, e.g., using singly labeled probes. These methods and reagents exploit advantageous properties of thiazine dyes and diazine dyes. Furthermore, the use of these light emission modifiers in background reduction, nucleic acid duplex stabilization and other uses is also described. Related kits, reaction mixtures and integrated systems are described.

Abstract: The invention relates to a thermocycler module for heating and/or cooling of a thermocycling device comprising a thermal switch, a heating block and a heat sink. The thermal switch comprises a thermoconducting liquid, e.g. a magnetic fluid or a liquid metal, and a stimulating unit, e.g. a magnetic unit or a Lorentz-force unit, for moving the thermoconducting liquid. The movement of the thermoconducting liquid provides, in an on-state of the thermal switch, a thermal connection between the heating block and the heat sink.
Abstract: Magnetic particles with an outer glass surface being essentially poreless or having pores of a diameter of less then 10 nm as well as ferromagnetic particles with a glass surface are preferentially useful for the isolation of biological material from samples. They provide a quick and reliable purification.
