    • Methods and kits are provided for a multiplexed reverse phase protein (RPP) microarray platform, which is utilized for simultaneous monitoring of cellular components following exposure to an agent or agents of interest. The microarray comprises cell lysates or fractions thereof. The array is probed with a specific binding agent or agents. Binding agents of interest include agents specific for inducible proteins, constitutive proteins, apoptosis-specific modifications, etc., and particularly for post-translationally modified proteins, e.g. phosphoproteins, glycosylated proteins, and the like. The methods are of interest for determining patterns of modifications, and the like that define disease states or classify subsets of disease (including staging and subsets of cancers, autoimmune diseases, and the like); that follow response to therapy; that determine response patterns after exposure to a specific agent, and the like. This information is useful in the development of therapies, as a disease prognostic, determining patient specific therapies, and the like. Kits may comprise microarrays having a cell selection of interest, and may further comprise antibodies of desired specificity, and the like.
    • 提供了用于多重反相蛋白(RPP)微阵列平台的方法和试剂盒,其用于在暴露于一种或多种感兴趣的试剂后同时监测细胞组分。 微阵列包含细胞裂解物或其部分。 该阵列用特定的结合剂或试剂进行探测。 感兴趣的结合剂包括对可诱导蛋白质,组成型蛋白质,细胞凋亡特异性修饰等特异的试剂,特别是对于翻译后修饰的蛋白质,例如蛋白质。 磷蛋白,糖基化蛋白等。 这些方法对确定修饰模式以及定义疾病状态或分类疾病亚组(包括癌症的分期和亚组,自身免疫性疾病等)是有意义的; 遵循疗法的反应; 确定暴露于特定试剂后的响应模式,等等。 这些信息在开发疗法,作为疾病预后,确定患者特异性疗法等方面是有用的。 试剂盒可以包含具有感兴趣的细胞选择的微阵列,并且可以进一步包含具有期望特异性的抗体等。
