The present invention relates to optionally automated methods that may be used to qualitatively and/or quantitatively detect at least one, or for example, two or more different targets in a sample, and kits associated with such methods. The two or more different targets may be detected and distinguished by adding at least one cross-linking agent to the sample in between different steps of a detection procedure. The addition of a cross-linking agent may allow for drastic changes in buffer conditions (i.e. solvent, pH, salt concentration, etc.) or temperature in order to refine a detection procedure with minimal loss of signal. The instant invention is compatible with a variety of detection systems, including immunohistochemistry (IHC), immunocytochemistry (ICC), in situ hybridization (ISH), flow cytometry, enzyme immuno-assays (EIA), enzyme linked immuno-assays (ELISA), blotting methods (e.g. Western, Southern, and Northern), labeling inside electrophoresis systems or on surfaces or arrays, and precipitation, among other general detection assay formats. The invention is also compatible with many different types of samples, targets, probes, and detectable labels.
本发明涉及可选自动化方法,用于在样品中定性和/或定量检测至少一个不同的目标或例如两个或更多不同的目标,并且与此类方法相关联的试剂盒。可以通过在检测过程的不同步骤之间添加至少一种交联剂来检测和区分两个或更多不同的目标。添加交联剂可以允许在最小信号损失的情况下在缓冲条件(即溶剂,pH,盐浓度等)或温度方面进行巨大的改变,以精细检测程序。本发明与各种检测系统兼容,包括免疫组织化学(IHC),免疫细胞化学(ICC),原位杂交(ISH),流式细胞术,酶免疫分析(EIA),酶联免疫分析(ELISA),印迹方法(例如Western,Southern和Northern),在电泳系统内或表面或阵列上标记,以及沉淀等其他一般检测分析格式。本发明还与许多不同类型的样品,目标,探针和可检测标签兼容。
