    八种新型氯化荧光蛋白标记探针的合成、光谱特性和生物学应用
    摘要:
    通过氯化间苯二酚与 3, 6-dichloro-4-carboxyphthalic anhydride 在甲磺酸存在下的反应,分 7 个步骤制备了八种带有接头和反应基团的新型氯化荧光蛋白标记探针。目标化合物和中间体的结构通过IR、MS、1H NMR和元素分析。研究了氯化荧光素的光谱特性。这些荧光探针在 508-536 nm 处显示吸收峰,在 524-550 nm 处显示出荧光峰。发现它们在长波长处具有吸收和发射最大值以及高荧光量子产率。随着氯的增加,氯化荧光素的发射光谱向长波长移动。这些探针用于细胞的荧光成像,以研究它们是否可以与细胞结合。活细胞的荧光成像显示它们位于细胞核中。然而,它们位于化学固定细胞的细胞质中。这些探针将是制备稳定荧光偶联物的有用试剂。

    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.
    本文披露了一种新型的醌甲烯类似物前体,以及使用该前体的方法和套件的实施例,用于检测生物样本中的一个或多个靶标。检测方法包括将样本与检测探针接触,然后将样本与包含酶的标记共轭物接触。酶与包含可检测标记的醌甲烯类似物前体相互作用,形成具有可检测标记的反应性醌甲烯类似物,该类似物与生物样本中的靶标近距离或直接结合。然后检测可检测标记。在某些实施例中,通过多个醌甲烯类似物前体与不同酶相互作用,无需酶去活化步骤即可检测多个靶标。
  • Photocleavable isotope-coded affinity tags

    This invention relates to agents and conjugates that can be used to detect and isolate target components from complex mixtures such as proteins and protein fragments from biological samples from in vivo and in vitro sources. Agents comprise a detectable group bound to a photoreactive group. Conjugates comprise agents coupled to substrates by covalent bounds which can be selectively cleaved with the administration of electromagnetic radiation. Targets substances labeled with detectable molecules can be easily identified and separated from a heterologous mixture of substances. Exposure of the conjugate to radiation releases the target in a functional form and completely unaltered. Using photocleavable molecular precursors as the conjugates, label can be incorporated into macromolecules, the nascent macromolecules isolated and the label completely removed. The invention also relates to targets isolated with these conjugates which may be useful as pharmaceutical agents or compositions that can be administered to humans and other mammals.
    本发明涉及可以用于检测和分离来自复杂混合物(如来自体内和体外源的生物样本中的蛋白质和蛋白质片段)的靶组分的试剂和结合物。试剂包括结合到光反应基团的可检测基团。结合物包括通过共价键结合到底物的试剂,这些共价键可以通过电磁辐射的施加而选择性地断裂。标记有可检测分子的目标物质可以很容易地从异源混合物中识别和分离出来。将结合物暴露于辐射会释放出目标物质以功能形式完全不变。使用光解分子前体作为结合物,标记可以被结合到大分子中,新生大分子被分离并标记完全去除。该发明还涉及使用这些结合物分离出的目标物质,这些目标物质可能作为药用剂或可用于给人类和其他哺乳动物的组合物。
