放射性标记物

耐热性碱性磷酸酯酶作为非放射性标记物的研究

Study on Thermostable Alkaline Phosphatase as Non radioactive Label

由于基于荧光、化学发光和生物发光分析的测定方法有低的检测限，且其标记物无毒性、安全、经济，可以代替放射性同位素作为标记物。

Because the methods based on fluorescence , chemiluminescence and bioluminescence have very low detects , they have the potential to replace assays that employ radioisotopes as labels .

应用基因转染技术，诱导肿瘤细胞表达某种表面抗原或受体，使肿瘤细胞能够选择性地摄取某一放射性核素或其标记物，以便能够应用放射性核素治疗恶性肿瘤。

This review presents an overview of gene transfection methods to genetically induce tumor cells to express enhanced levels of cell surface antigens and receptors to intake radiolabeled antibody and peptide targeting and thus increase their therapeutic effect in radiotherapy .
