不同细胞群的分离一直是细胞生物学家及免疫学家感兴趣的问题。为了研究不同细胞群或亚群的生物学功能以及它们之间的相互关系。必须迅速有效地在温和条件下进行细胞分离。利用物理性质进行分离的方法有:密切梯度离心、沉降法、细胞电泳等。利用生疫学性质进行分离的方法有:免疫吸附法等。近年来由于单克隆抗体技术的发展使磁性细胞分离技 Isolation of different cell populations has long been of interest to cell biologists and immunologists. In order to study the biological functions of different cell populations or subpopulations and the interrelationships between them. The cells must be rapidly and efficiently isolated under mild conditions. The use of physical properties of the separation methods are: close gradient centrifugation, sedimentation, cell electrophoresis. The use of the nature of the separation methods are: immunoadsorption method. In recent years due to the development of monoclonal antibody technology to magnetic separation technology
