    • The present invention concerns in general the field of antigen-antibody-interaction-based analysis-methods and kits therefore. In particular, the present invention concerns a method for a quantitative in vitro analysis to diagnose, to categorise, to predict and/or to monitor the progression of a condition comprising contacting a sample suspected of containing anti-A-antibodies from a subject to be analysed with native and mutant antigen A, wherein the binding to mutant antigen A helps to eliminate unspecific binding to antigen A and furthermore helps to eliminate individual patient based artefacts, so that clear and unbiased data for the formation of complexes of anti-A-antibodies and antigen A are obtained. The present invention also relates to a kit for carrying out such a method. For example, the antigen is the MOG protein, and it is used as a marker for Multiple Sclerosis.
    • 因此,本发明一般涉及基于抗原 - 抗体相互作用的分析方法和试剂盒的领域。 特别地,本发明涉及用于诊断,分类,预测和/或监测病症进展的定量体外分析的方法,包括将来自受试者的怀疑含有抗A抗体的样品与 用天然和突变抗原A进行分析,其中与突变抗原A的结合有助于消除与抗原A的非特异性结合,并且进一步有助于消除单独的基于患者的人工制品,从而形成抗A抗体复合物的清晰和无偏见的数据 并获得抗原A. 本发明还涉及一种用于执行这种方法的套件。 例如,抗原是MOG蛋白,并且它被用作多发性硬化症的标记物。
