    • The present invention relates to an antigenic fusionprotein, which carries multiple Galα1,3Gal epitopes. The fusion protein according to the invention may also be comprised of a heavily glycosylated mucin part, which mediates binding to selectins, such as PSGL-1, and a part, which exhibits immunoglobulin properties, such as the Fc part of IgG. The fusionprotein according to the invention is preferably used as an absorber to prevent a hyperacute rejection of a xenotransplant, such as a pig tissue or organ transplanted into a human patient. In addition, the invention relates to a method for the prevention of a hyperacute rejection reaction in a patient who is to receive a xenotransplant.
    • 本发明涉及携带多种Galalpha1,3Gal表位的抗原融合蛋白。 根据本发明的融合蛋白还可以由介导与选择蛋白结合的重糖基化粘蛋白部分(例如PSGL-1)和显示免疫球蛋白特性的部分(例如IgG的Fc部分)组成。 根据本发明的融合蛋白优选用作吸收剂以防止异种移植物例如移植到人类患者中的猪组织或器官的超急性排斥反应。 此外,本发明涉及一种用于预防接受异种移植的患者中的超急性排斥反应的方法。
