Protein til immunkastration af pattedyr

Fusion protein for immunocastration (Sequences 1a and 1b) that comprises the primary amino acid sequence of the gonadotrophin-liberating protein fused to a theoretical sequence: Sequence 1a NH 2 - QHWSYGLRPG GPPFSGGGGPPFSA-COOH Sequence 1b NH 2 -GPPFSGGGGPPFSA QHWSYGLRPG-COOH; DNA sequences coding for said fusion protein; vaccine comprising said fusion protein; use of the fusion protein for mammal immunocastration; process for producing the vaccine; process for preparing the fusion protein that comprises fusing the amino acid sequence of the gonadotrophin-liberating hormone (GnRH-I) to a theoretical glycosilable sequence having immunogenic activity that does not include pathogen or "carrier" protein sequences in its structure.
