We report an efficient procedure for in situ hybridization with a multi-well format on Caenorhabditis elegans embryos for large scale screening of gene expression patterns in this organism. Each hybridization well contains embryos at various stages throughout embryogenesis. The validity of the method was confirmed through results with control genes whose expression patterns have been reported; glp-1 in very early embryos, myo-2 in pharyngeal muscle and unc-54 in body wall muscle. Several collagen genes and a pepsinogen gene were also examined to establish a set of lineage-specific markers. As a pilot project, we examined approximately 100 unique cDNA species classified by our cDNA project, finding that approximately 10% of the cDNA groups were expressed in specific cells and at specific stages.
我们报道了一种在秀丽隐杆线虫胚胎上进行多孔原位杂交的高效方法,用于大规模筛选该生物体中的基因表达模式。每个杂交孔都包含处于胚胎发育各个阶段的胚胎。通过使用已报道其表达模式的对照基因的结果,证实了该方法的有效性;在极早期胚胎中的glp-1、咽肌中的myo-2和体壁肌中的unc-54。还检查了几个胶原蛋白基因和一个胃蛋白酶原基因,以建立一组谱系特异性标记。作为一个试点项目,我们检查了约100种由我们的cDNA项目分类的独特cDNA物种,发现约10%的cDNA组在特定细胞和特定阶段表达。
