  Particular disclosed embodiments disclosed herein concern using a one or more various mass tags, which can be specifically deposited at targets through direct or indirect enzymatic-catalyzed transformation, to provide a method for identifying targets in tissue samples. The mass tags may be labeled with stable isotopes to produce mass tags having the same chemical structure but different masses. Mass codes produced by ionizing the mass tags are detected and/or quantified using mass spectrometry. The method can be used for multiplexed detection of multiple targets in a particular sample. In some embodiments, a map divided into sections representing sections of the tissue sample may be prepared, with the map sections including data corresponding to quantification data wherein the size of a mass peak is determined and correlated with the amount of a target for the corresponding tissue sample section.

  本文所公开的具体实施方案涉及使用一种或多种不同的质量标记，通过直接或间接的酶催化转化特异性地沉积在靶标上，从而提供一种识别组织样本中靶标的方法。质量标签可以用稳定同位素标记，以产生化学结构相同但质量不同的质量标签。通过电离质量标签产生的质量代码可使用质谱法进行检测和/或定量。该方法可用于特定样品中多个目标的多重检测。在某些实施方案中，可制备代表组织样本切片的图谱，图谱切片包括与定量数据相对应的数据，其中质量峰的大小被确定并与相应组织样本切片的靶标量相关联。

  Disclosed herein are novel quinone methide analog precursors and embodiments of a method and a kit of using the same for detecting one or more targets in a biological sample. The method of detection comprises contacting the sample with a detection probe, then contacting the sample with a labeling conjugate that comprises an enzyme. The enzyme interacts with a quinone methide analog precursor comprising a detectable label, forming a reactive quinone methide analog, which binds to the biological sample proximally to or directly on the target. The detectable label is then detected. In some embodiments, multiple targets can be detected by multiple quinone methide analog precursors interacting with different enzymes without the need for an enzyme deactivation step.
