    • An improved method for detection of agents in an analyte sample from a mammal, which agents will stimulate mononuclear cells to release factors for endothelial cell activation. The method is based on the discovery that an indirect pathway for endothelial cell activation mediated by mononuclear blood cells is substantially more efficient in stimulating the production of cytokines and cell adhesion molecules by endothelial cells than a direct, serum-dependent pathway. The method of the invention therefore utilizes the indirect pathway to activate cultured endothelial cells by exposing them to an amplification mixture comprising the analyte sample and mononuclear blood cells. Activation, if any, of the cultured endothelial cells is then determined by described detection means. Using this improved method, mononuclear cell stimulatory agents (such as inflammatory agents) can be detected in an analyte sample at picomolar or greater concentrations.
    • 用于检测来自哺乳动物的分析物样品中的试剂的改进方法,所述试剂将刺激单核细胞释放内皮细胞活化因子。 该方法基于以下发现:由单核血细胞介导的内皮细胞活化的间接途径在内皮细胞刺激细胞因子和细胞粘附分子的产生方面比直接的血清依赖性途径更有效。 因此,本发明的方法利用间接途径将培养的内皮细胞暴露于包含分析物样品和单核血细胞的扩增混合物中。 然后通过描述的检测手段确定培养的内皮细胞的活化(如果有的话)。 使用这种改进的方法,可以在皮摩尔浓度或更高浓度的分析物样品中检测单核细胞刺激剂(如炎症剂)。
