Abstract: The invention concerns a device for withdrawing samples of liquid samples for analytical elements. The capillary-device channel is essentially formed by a carrier, a cover and optionally an intermediate layer between the cover and carrier. A notch is located in one of the surfaces forming the channel capable of capillary liquid transport at the edge of the test element forming the sample application opening so that one side of the edge of the test element forming the sample application opening is at least partially discontinuous and the surface opposite to the notch is exposed. It also concerns a method for withdrawing a liquid sample into an analytical element with the aid of a device according to the invention.
Abstract: The present invention concerns a method for the determination of apoptotic products in samples taken from patients in which apoptosis is induced as a result of disease or therapy, which is characterized in that the concentration of the apoptotic products in samples taken from patients is correlated with the effectiveness of the therapy and thus serves as a follow-up for the therapy. The serum samples are taken at various times and determined. The present invention in particular concerns a method in which the concentration of nucleosomes is determined in serum samples of tumour patients in order to assess the effectiveness of tumour therapy. Furthermore the present invention also concerns the use of a method according to the invention to determine the effectiveness of therapy in tumour patients who are subjected to a radiotherapy or chemotherapy treatment as well as in patients after an acute ischaemic event or after hypothermia treatment.

Abstract: The present invention relates to oxidoreductase apoenzyme variants which are enzymatically inactive but have coenzyme-binding properties. Further, the present invention relates to DNA sequences encoding these oxidoreductase apoenzyme variants, expression vectors containing such DNA sequences and the use of these oxidoreductase apoenzyme variants in diagnostic applications.
Abstract: The present invention concerns processes for the production of dry, partially amorphous products containing biologically active and in particular therapeutically active material which are macroscopically homogeneous substance mixtures, the substance mixtures being selected from at least one substance of each of the groups (i) carbohydrate or zwitterion with a polar residue and derivatives thereof, and (ii) zwitterion with an apolar residue and derivatives thereof, wherein a solution is prepared of the biologically or therapeutically active material and of substances (i) and (ii) and the solution is dried at a product temperature above the freezing point of the solution. In addition the invention concerns new substance mixtures which are obtained by the said process as well as the use thereof in diagnostic or therapeutic methods.
Abstract: The invention concerns an arrangement for determining the concentration of glucose in a tissue fluid. In the microdialysis technology used for this purpose, perfusate-containing glucose is transported in intermittent delivery pulses through a microdialysis probe inserted into the tissue fluid and dialysate obtained in this process is passed to a measuring cell to record the glucose content. In order to achieve an exact determination of glucose even with a reduced dialysis period, it is proposed that the starting content of glucose in the perfusate is adapted to the glucose content of the tissue fluid by means of a control device in accordance with a command variable derived from the measurement signals of the measuring cell. When the control deviation is negligible the momentary starting content of glucose in the perfusate can be determined as a measure for the glucose content of the tissue fluid.
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.
