    • One aspect of the present invention relates to methods and compositions for attenuating xenograft rejection by administering, to an animal receiving the xenograft, an amount of a polymer-derivatized xenoantigen (hereinafter nullxenopolymernull) effective for inhibiting or lessening the severity of hyperacute rejection response (HAR), or other immunological response to the graft, that is dependent on the presence of the xenoantigen on the grafted tissues or cells. In certain embodiments, the xenopolymer is administered in an amount sufficient to neutralize host antibodies (nullxenoreactive antibodiesnull or nullXNAnull) immunoreactive with the xenoantigen. The xenopolymer may additionally, or alternatively, be used as a tolerogen (or anergen) for the xenoantigen, e.g., able to suppress, to some degree, the production/secretion of XNAs by the immune system of the host.
    • 本发明的一个方面涉及通过向接受异种移植物的动物施用一定量的有效抑制或减轻超急性排斥反应严重性的聚合物衍生的异种抗原(以下称为“异戊烯”)来减弱异种移植排斥的方法和组合物 (HAR)或其他对移植物的免疫应答,这取决于移植组织或细胞上异种抗原的存在。 在某些实施方案中,以足以中和与异种抗原免疫反应的宿主抗体(“异反应性抗体”或“XNA”)的量施用异种聚合物。 异源聚合物可以另外地或替代地用作异种抗原的耐受原(或过敏原),例如能够在一定程度上抑制宿主的免疫系统产生/分泌XNA。

    • The invention concerns a biocompatible polymer having a mole weight more than 50000 g/mole, preferably 90000 g/mole for fixing biological ligands comprising at least a first linear segment consisting of a hydrophobic homopolymer derived from polymerisation of a hydrophobic monomer A; a second linear segment consisting of a hydrophilic polymer derived from copolymerisation of a monomer B bearing a reactive function X and a hydrophilic monomer C not bearing any reactive function, said second segment being covalently bound to one end of the first segment. The invention also concerns a biological polymer-ligand-conjugate, a device for capturing a target molecule comprising a solid support whereon is immobilised a biological polymer-ligand conjugate and methods for preparing said polymer. The invention is mainly applicable in the field of diagnosis.
    • 本发明涉及摩尔重量大于50000克/摩尔,优选90000克/摩尔的生物相容性聚合物,用于固定生物配体,其包含至少一种由衍生自疏水性单体A的聚合的疏水性均聚物组成的第一线性区段; 第二线性区段由亲水性聚合物组成,所述亲水性聚合物衍生自携带反应性官能团X的单体B与不具有任何反应性功能的亲水性单体C的共聚,所述第二区段共价结合到第一区段的一端。 本发明还涉及生物聚合物 - 配体 - 缀合物,用于捕获包含其中固定有生物聚合物 - 配体缀合物的固体支持物的靶分子的装置和用于制备所述聚合物的方法。 本发明主要适用于诊断领域。
