    • The invention provides a fragment of C1q which is characterized in that a plurality of such fragments selectively binds immune complexes or aggregated immunoglobulins in the presence of monomeric immunoglobulin. The invention also provides a synthetic peptide comprising the sequence [SEQ ID NO 2]: Leu Glu Gln Gly Glu Asn Val Phe Leu Gln Ala Thr or variants thereof capable of binding immunoglobulin. Like the C1q fragment, a plurality of the peptides can selectively bind immune complexes or aggregated immunoglobulins in the presence of monomeric immunoglobulin. As a result of this property, the fragments and peptides are well-adapted for removing immune complexes and aggregated immunoglobulins from fluids containing monomeric immunoglobulin, and for detecting or quantitating immune complexes in such fluids. The invention also provides a binding material for removing immune complexes or aggregated immunoglobulins from a fluid. The binding material comprises plural binding peptides, the peptides being characterized in that a plurality of them selectively binds immune complexes and aggregated immunoglobulins in the presence of monomeric immunoglobulin. The invention also provides methods of treating an inflammatory response and prolonging the survival of transplanted tissue.
    • 本发明提供C1q的片段,其特征在于多个这样的片段在单体免疫球蛋白存在下选择性结合免疫复合物或聚集的免疫球蛋白。 本发明还提供了包含序列[SEQ ID NO 2]:Leu Glu Gln Gly Glu Asn Val Phe Leu Gln Ala Thr或能够结合免疫球蛋白的变体的合成肽。 与C1q片段一样,多个肽可以在单体免疫球蛋白存在下选择性地结合免疫复合物或聚集的免疫球蛋白。 作为该性质的结果,片段和肽适合于从含有单体免疫球蛋白的流体中除去免疫复合物和聚集的免疫球蛋白,并用于检测或定量这些流体中的免疫复合物。 本发明还提供了用于从流体中除去免疫复合物或聚集的免疫球蛋白的结合材料。 所述结合材料包含多个结合肽,所述肽的特征在于其多个在单体免疫球蛋白存在下选择性结合免疫复合物和聚集的免疫球蛋白。 本发明还提供了治疗炎症反应并延长移植组织存活的方法。

    • A method of binding aggregated immunoglobulin or immune complexes comprising contacting them with modified forms of C-reactive protein. The method may be employed for diagnostic and therapeutic purposes and to deplete fluids of aggregated immunoglobulin or immune complexes. Further, a method of reducing the levels of immune complexes in a mammal comprising administering modified-CRP to the mammal, and a method of binding immunoglobulins comprising contacting them with modified C-reactive protein. Also, a method of binding aggregated immunoglobulin or immune complexes comprising contacting them with antibody to neo-CRP, and a method of modifying C-reactive protein. Finally, a test kit for detecting or quantitating immune complexes and a device for removing aggregated immunoglobulin or immune complexes from fluids are disclosed.
