    • In certain aspects, the present invention provides methods and compositions for determining whether a cancer cells is likely to respond to treatment with a Her 1 -acting agent. In one aspect, the invention provides a method for determining whether a cancer cell is likely to respond to treatment with a Her 1 -acting agent, comprising detecting on the cancer cell at least about 600 Her 1 -Her 1 dimers, wherein the presence of the at least about 600 Her 1 -Her 1 dimers indicates that the cancer is likely to respond to treatment with the Her 1 -acting agent. In another aspect, the invention provides a method for determining whether a cancer cell is likely to respond to treatment with a Her 1 -acting agent, comprising detecting on a cell of the cancer at least about 600 Her 1 -Her 1 dimers, at least about 1000 Herl-Her2 dimers, and fewer than about 1000 Her2-Her3 dimers, wherein the presence of the at least about 600 Her 1 -Her 1 dimers, the at least about 1000 Herl-Her2 dimers, and the fewer than about 1000 Her2-Her3 dimers indicates that the cancer cell is likely to respond to treatment with the Her 1 -acting agent. Preferably, methods of the invention are implemented by using sets of binding compounds having releasable molecular tags that are specific for multiple components of one or more types of receptor dimers. After binding, molecular tags are released and separated from the assay mixture for analysis.
    • 在某些方面,本发明提供了用于确定癌细胞是否可能对Her 1处理剂的治疗有反应的方法和组合物。 一方面,本发明提供了一种用于确定癌细胞是否可能对Her1处理剂起反应的方法,包括在癌细胞上检测至少约600个Her 1 -Her 1二聚体,其中存在 至少约600个Her 1 -Her 1二聚体表明癌症可能对她用1代谢剂的治疗有反应。 在另一方面,本发明提供了一种用于确定癌细胞是否可能对Her 1处理剂有反应的方法,包括至少检测至少约600个Her 1 -Her 1二聚体的癌细胞 约1000个Herl-Her2二聚体和少于约1000个Her2-Her3二聚体,其中存在至少约600个Her1-Her2二聚体,至少约1000个Her1-Her2二聚体,以及少于约1000个Her2-Her2二聚体 -Her3二聚体表明癌细胞很可能对Her1处理剂有反应。 优选地,通过使用具有对一种或多种类型的受体二聚体的多种成分特异的可释放分子标签的组合化合物来实现本发明的方法。 结合后,将分子标签从测定混合物中释放并分离出来进行分析。
