The invention of novel protein microarrays and protein microarray-based techniques to determine the presence and amounts of proteins of interest are described. These microarrays and methods of use can be used for the simultaneous detection of a multiplicity of antigens or antibodies in a high throughput assay based upon the differential affinity of molecules for one another. The microarrays can be formed by immobilizing capture proteins in an array on a membrane. Analytes of interest can be bound by the capture proteins and can be detected either by the position to which they are immobilized or by the identity of detecting proteins or agents which bind to the analytes of interest. The interactions that can be detected using the present invention can also be used to characterize proteins of unknown identity or character.
本发明描述了新型蛋白质微阵列和基于蛋白质微阵列的技术,以确定相关蛋白质的存在和数量。这些微阵列及其使用方法可用于在高通量检测中同时检测多种抗原或
抗体,其依据是分子之间的亲和力不同。微阵列可以通过将捕获蛋白固定在膜上的阵列中形成。感兴趣的分析物可与捕获蛋白结合,并可通过它们被固定的位置或与感兴趣的分析物结合的检测蛋白或制剂的特性进行检测。使用本发明可检测到的相互作用也可用于鉴定身份或特性不明的蛋白质。
