  • Protein homologue of human angiogenin
    Patent number: 5171845
    Abstract: The invention concerns a new protein of approximately 17 KD, with angiogenic activity, a process for isolating it from mammalian milk, therapeutic compositions containing it, a process for detecting and/or determining the content of mammalian angiogenins, their homologues and their fragments. Said protein, of bovine origin, has a sequence of 125 aminoacids, 81 of which are common to human angiogenin, and a molecular weight of approximately 17 KD, and is extracted from mammalian milk. Application to the detection of mammalian angiogenin.

  • Immunogenic fraction active against bilharzioses, its preparation, and immunizing compositions containing it
    Patent number: 5021560
    Abstract: The present invention relates to an immunogenic fraction active against bilharzioses. This glycoprotein extracted from hemocyanin of a mollusc, is characterized in that its glucidic fraction represents 5 to 25% of the glycoprotein molecule and in that the molar composition of said glucidic fraction (calculated on the basis of 3 mannose residues) is substantially the following:______________________________________ Monosaccharidic residues ______________________________________ Mannose 3 Galactose 3 to 4 Fucose 2 to 3 Glucose 2 .+-. 0.2 Xylose 0.5-1 N-acetylglucosamine 3-4 N-acetylgalactosamine 2 .+-. 0.3 ______________________________________Use: immunizing compositions against bilharzioses.
