  • Patent number: 7759071
    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 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.

  • Patent number: 6406672
    Abstract: A capillary hematocrit separation structure is included within a housing having a fluid inlet port, a reaction region, and a capillary pathway connecting the inlet port and the reaction region. The capillary pathway is dimensioned so that the driving force for the movement of liquid through the capillary pathway arises from capillary pressure. A plurality of obstructions are fixed in the capillary pathway, each obstruction having a concave portion facing toward the vented reaction region on the down stream side of the obstructions as viewed with reference to a liquid flowing from the inlet port to the reaction region. The capillary pathway in a hematocrit separation structure for a single drop sample size includes about 105 obstructions, each obstruction including a concave portion having a volume of between about 10−4 to 10−5 &mgr;l for selectively receiving hematocrit.

  • Patent number: 6093546
    Abstract: The invention relates to a process for making a test element, such as an analytical test element. Compositions of matter, such as analyte specific receptors, are treated to carry a charge. These are then applied to test carriers treated to carry a charge opposite that of the composition of matter. Interaction of charge fixes the composition of matter to the test element.
