  • Patent number: 6994210
    Abstract: A conveyor belt (2) includes a reinforcement (4) built up of at least one reinforcement layer (4a, . . . ) which includes fabric or cord and cover plates (8a, 8b) can be arranged on the carrier side and/or running side with the cover plates being made of elastomer or a rubber mixture. In order to prevent baking-on and dirtying during transport of the different goods, especially mass goods, the conveyor belt (2) is provided with a practice-proven durable and permanent anti-adhering surface. A plastic coating (10) is applied to the conveyor belt (2) on the carrier side and is an anti-adhering coating. The plastic coating (10) preferably is made of ultra high molecular polyethylene. The polyethylene foil (10) can be vulcanized to the carrier side cover plate (8a) or, in lieu of the carrier side cover plate (8a), the polyethylene foil can be vulcanized directly to the reinforcement (4) comprising at least one rubberized reinforcement layer (4a, . . . ).

  • Patent number: 6419925
    Abstract: The present invention relates to the identification of toxoplasma gondii antigens and the preparation thereof by genetic engineering. A cDNA expression gene bank of this parasite was prepared. Recombinant clones which are of diagnostic interest were identified using a high-titer rabbit anti-Toxoplasma gondii serum, and isolated.

  • Patent number: 5457089
    Abstract: The invention relates to muteins of human erythropoietin (EPO) in the carboxyl terminal region which are prepared by means of recombinant DNA techniques. These mutants have advantageous properties in comparison with human wild-type EPO.

  • Patent number: 5395614
    Abstract: Protective Plasmodium falciparum hybrid proteins which contain part-sequences of the malaria antigens HRPII and SERP, the preparation and use thereof.The invention relates to hybrid proteins composed of part-sequences of the malaria antigens HRPII and SERP. The HRPII sequence has already proven protective in the monkey model (EP-A2-0 315 085), where a C-terminal region of 189 amino acids has been used in the present invention in the same way as in the preceding protection experiment. SERP was identified with the aid of an antiserum against a protective protein band (EP-A1-0 283 882); the part-sequence used (amino acids (AA) 631-892 or 630-764) contains at least two T-cell epitopes (Roussilhon et al. (1990), Immunol. Letters 25, 149-154). In preferred embodiments, further T-cell epitope-containing regions of other P. falciparum proteins such as merozoite surface antigen I (MSA I or else "195 kd antigen"), amino acids from 100 to 300, are incorporated (Crisanti et al. (1988), Science 240, 324-326).

  • Patent number: 5393523
    Abstract: Recombinant histidine-rich protein of Plasmodium falciparum, its preparation and use. It was possible, by screening two different Plasmodium falciparum cDNA gene banks with an antiserum against a 41 kD protein and by cross-hybridization with the insert DNA of a clone obtained therewith, to isolate a gene which codes for a Histidine-Alanine-rich protein (HRP-II). This protein protects aotus monkeys from infection with P. falciparum and is thus a suitable constituent of a malaria vaccine.

  • Patent number: 5194587
    Abstract: The invention relates to malaria-specific DNA sequences, to the expression products thereof, and to the use thereof.A combination of three of the expression proteins whose DNA sequences were isolated by screening a lambda gt11 gene bank with a monospecific antiserum against the protective 41kD antigen bend from P. falciparum protects Aotus monkeys completely from a P. falciparum infection in model experiments.
