在免疫学领域，了解进展对疫苗，感染或肿瘤的免疫反应，反应之后往往随着时间的推移。同样，淋巴细胞稳态的研究需要时间课程实验。这些研究是在相同的鼠标理想，以减少实验的变异，以及使用的老鼠数量。抽血时间课程实验允许的性能，但它只能提供约外周血淋巴细胞的信息，并提供数量有限的细胞1-4。由于通过人体循环和居住在淋巴结中的淋巴细胞有不同的特性，重要的是要检查这两个地方。淋巴结顺序切除手术提供了一个独特的机会，后续的免疫反应或免疫细胞膨胀，随着时间的推移相同的鼠标。此外，这种技术的产生，这是足够的PE 1-2X10 6个淋巴结细胞之间rform表型特征和/或功能分析。顺序淋巴结手术或淋巴结清扫已成功地应用于我们和其他国家5-11。在这里，我们描述如何可以通过一个小切口，在皮肤一个anesthetised鼠标删除臂丛和腹股沟淋巴结肿大。由于手术是肤浅的，并迅速完​​成，鼠标恢复速度非常快，愈合好，不会遇到过多的疼痛。每隔一天，有可能收获一个或两个淋巴结允许时间课程实验。因此，该技术是适合学习节点居住淋巴细胞淋巴结的特点，随着时间的推移。这种方法适用于各种实验设计，我们相信，许多实验室将受益于执行顺序淋巴结手术。
