描述了一种使用荧光相关光谱 (FCS) 测量蛋白质在原代免疫细胞膜中扩散的方法。在本文中,说明了抗体用于荧光标记的用途。

该方案的总体目标是使用荧光相关光谱测量标记蛋白在原代免疫细胞膜中的扩散速率。这种方法可以帮助确定免疫学和细胞生物学领域的关键问题,例如识别具有更活跃膜受体动力学的自然杀伤细胞。这种技术的主要优点是它与活细胞一起使用,因此它准确地反映了分子运动的自然状态。

如果不同的自然杀伤细胞特征(例如分子扩散)与其功能相关联,则可以更好地预测效率,那么该技术的意义将扩展到癌症的免疫疗法。虽然这种方法可以深入了解免疫细胞中的分子运动,但它也可以应用于任何学科的其他原代细胞和细胞系。在专家模式下打开软件,并选中 Scan New Images 选项。
