先前的研究表明，ISH适用于探测多个目标RNA16、17、18。,17,18在此协议中，我们描述了一种高分辨率ISH方法，用于检测共分液中的mRNA，并强调西潘库鲁斯核糖的优化杂交条件。我们观察到的dmrt1的明显信号证明了该协议在基因表达检测中的成功应用（图2）。
在实验中，需...

ISH，使用标记的核酸探针来检测特定的DNA或RNA感兴趣的序列，是描述形态保存组织11、2、32,3中目标基因的空间表达模式的有用方法。通常，目标序列由聚合酶链反应（PCR）生成，然后用作模板，合成标有二戈西根尿碱-5'-三磷酸的抗感觉/感觉RNA探针。样品在用核试探孵育前固定并渗透。洗掉多余的探针后，利用抗地氧辛抗体，即碱性磷酸酶33、4、5、6，4,5,6通过免疫组织化学进行可视化。
西潘库鲁斯努杜斯（菲勒姆·西潘库拉;命令西潘库利达：西潘库利达）是一种未分割、共和和双边对称的海虫77、8。8虹食核生物是一种国际性物种，广泛分布于热带和温带沿海水域。也是中国南方重要的海洋渔业资源，因其高营养和药用价值9,9，10。然而，分子生物学中的西普库鲁斯核苷也还处于起步阶段。为了充分理解基因的生物作用，对细胞分辨率下的基因表达模式进行调查是十分感兴趣的。在非模型生物Sipunculusnudus中，ISH方法是检测基因表达模式的理想方法，但至今尚未建立。其共母体流体包含多种细胞类型，包括粒细胞、urn细胞、细胞、生殖细胞、红细胞等11种。双性/mab-3相关转录因子1（dmrt1），作为这种方法的代表性基因，是一种高度保守的转录调节器，在大多数物种，从无脊椎动物到哺乳动物12，13。,13在一系列物种中（如黑色毛孔等）14 14，dmrt1表示在Sertoli细胞，围绕生殖细胞，其功能类似于西潘库鲁斯核细胞的营养细胞。因此，我们假设，虹膜核糖的dmrt1表示在精子的营养细胞中，ISH方法的结果明确证实了这一假设。
该协议首次描述ISH，用二戈西根宁标记的抗感觉/感觉mRNA探针，以确定mRNA表达模式在其共发流体涂片。提供最佳反应条件，允许在高分辨率下对mRNA表达进行非常敏感的可视化。开发的ISH方法可能应用于西潘库利达物种以外的西普库利达物种。
