细胞间连接是乳腺阶段特异性功能和发育的必需条件。该手稿提供了一个详细的方法,用于研究蛋白质 - 蛋白质相互作用(PPI)和使用鼠乳腺的共定位。这些技术允许调查不同发育阶段的细胞间连接之间的物理联系的动力学。

该方法的总体目标是确定两个或多个细胞间连接蛋白是否在细胞内共定位,并通过免疫共沉淀进一步评估它们的物理相互作用。这种方法可以帮助回答乳腺领域生物学中的关键问题,包括连接在正常发育和乳腺癌等疾病中的作用。该技术的主要优点是它可以以相对较低的成本提供有关体内蛋白质-蛋白质相互作用的重要信息。

要进行免疫荧光染色,请从冰箱中取出适当的显微镜载玻片。立即将切片在室温下浸入 4% 的甲醛中 15 分钟,以固定切片。然后,在室温下将载玻片浸入磷酸盐缓冲盐水中。
