然后通过免疫磁性细胞分选技术分离出播散的肿瘤细胞并进行培养，对培养成活的肿瘤细胞在鉴定来源的同时进行生物学活性检测，从细胞学角度判断入血肿瘤细胞形成转移灶的能力。
Secondly, we separated the tumor cells in blood samples by IMS and cultured it carefully, activities of the tumor cells has been tested to confirm their ability to form a successful metastasis.
因此，自70年代以来，磁性微球作为一种新型的功能材料，在细胞分离、蛋白质提纯、免疫测定和靶向药物等诸多领域有着广阔的应用前景。
Therefore, since 1970's, as a new type of functional material, it has gained broad applications in cell separation, protein purification, immunoassays, immobilized enzyme and target delivery of drug.
