Abstract: The invention concerns a device and method for withdrawing samples of liquid samples for analytical elements. The device includes a carrier and a cover with a surface that cooperates with a surface of the carrier to form a channel. The channel has an opening defined by at least one edge. At least one notch in the form of a partial groove extends into the at least one edge of the opening so that one side of the edge of the opening is at least partially interrupted by the at least one notch. The notch forms a sample application opening by exposing the surface, whose extension forms an inner surface of the channel.
Abstract: A purified thermostable enzyme is derived form the thermophilic archaebacterium Thermococcus gorgonarius. The enzyme can be native or recombinant, retains approximately 90% of its activity after incubation for two hours at 95° C. in the presence of stabilizing agents and possesses 3?-5? proofreading exonuclease activity. Thermostable DNA polymerases are useful in many recombinant DNA techniques, especially nucleic acid amplification by the polymerase chain reaction (PCR).

Abstract: The invention concerns a process for the immunological determination of a specific antibody in a fluid sample. The process involves incubating the fluid sample in the presence of a solid phase with two antigens directed against the antibody whose presence is to be determined; the first antigen carries at least one marker group, while the second is either (a) bonded to the solid phase or (b) present in a form in which it can bond with the solid phase, and betrays the presence of the antibody being sought by showing the presence of the marker group in the solid phase and/or in the fluid phase. The proposed process is characterised by the fact that at least one of the two antigens has several epitopic regions which react with the antibody to be determined.

Abstract: Within oligonucleotides 2-azapurine and especially 2-azaadenine bases form specifically base pairs with guanine. This base pair is of analogous stability as an adenine-thymine but less stable than a guanine-cytosine base pair. Therefore, the incorporation of 2-azaadenine residues into oligonucleotides instead of cytosine leads specifically to hybridization complexes with nucleic acids with homogenous stability. This is useful for the adaptation of the stabilities of different oligonucleotide sequences in all kinds of hybridization techniques, for example in oligomer chip technology.

Abstract: The present invention relates to new nucleic acid sequences derived from the ITS (Internal Transcribed Spacer) region, between the 16S and 23S rRNA genes, to be used for the specific detection and/or identification of Serratia species, in particular of Serratia marcescens, Serratia ficaria and/or Serratia fonticola, in a biological sample. The present invention relates also to a method for the specific detection and/or identification of Serratia species, in particular Serratia marcescens, Serratia ficaria and/or Serratia fonticola, using said new nucleic acid sequences derived from the ITS region. It relates also to nucleic acid primers to be used for the amplification of said spacer region of Serratia species in a sample.
Abstract: A storage container for holding analytical devices, the storage container being made of a rigid material and containing separate chambers in each of which at most one analytical device can be accommodated, wherein the chambers are in a regular geometric arrangement in relation to one another and each of the chambers has at least two opposite openings each sealed by a foil, wherein at least one of the chambers comprises a means for fixing the position of an analytical device in the chamber. In addition the invention concerns a system for storing analytical devices containing a storage container according to the invention and two or more analytical devices.

Abstract: A flat-shaped functional overlay for at least one region of a flat-shaped flexible object which does not form a fold when the sandwich composed of the flexible object and overlay is bent towards the side on which the overlay is located is described. The overlay is composed of one or several flat-shaped overlays which are attached to the flexible object in such a way that a part of their surface can move freely relative to the surface of the object covered by this part in the direction of curvature produced when the object is bent. In addition diagnostic test strips are described which have such an overlay.

Abstract: Magnetic particles are prepared containing a magnetic core coated with a glass layer having a substantially pore-free glass surface or having pores with a diameter of less than 10 nm. The particles are used for separating biological material such as nucleic acids. A preferred process of preparing the particles is by forming a mixture of magnetic cores with a sol formed from an alcohol and a metal alkoxide, spray-drying the mixture to coat the cores with a layer of gelled sol, and heating the coated cores to obtain the magnetic glass particles. Preferably, the particles have an average particle size of less than 100 ?m. The magnetic core may be a composite material containing a mica core and magnetite particles immobilized on the mica core, and the glass layer may contain boron oxide. Magnetic core materials include magnetite (Fe3O4) and Fe2O3.
