    • The invention relates to methods and system for detecting ligand binding to membrane receptors and endocytosis. A method for detecting ligand binding to a membrane receptor includes the steps of: incubating the cell with a dye and a ligand; and detecting dye-containing endocytic vesicles in the cell. A system for screening ligand binding to membrane receptors includes an automatic liquid handling device; an x-y stage for positioning a plate; a microscope configured to image endocytic vesicles of a cell; a software for automatic analysis of FM spots (endocytic vesicles); and a control unit configured to control the movement of the x-y stage and the microscope.
    • 本发明涉及检测配体结合膜受体和内吞作用的方法和系统。 检测配体与膜受体结合的方法包括以下步骤:将细胞与染料和配体一起孵育; 并检测细胞中含有染料的内吞囊泡。 用于筛选与膜受体结合的配体的系统包括自动液体处理装置; 用于定位板的x-y台; 显微镜,配置成图像细胞的胞吞泡; 用于自动分析FM斑点(内吞囊泡)的软件; 以及控制单元,被配置为控制x-y台和显微镜的移动。
