查询词典 radioactive

Prepare 131I-labbelled anti-CD20 monoclonal antibody using lodogen iodine labelling;(2)Measure the immunity activation of labbelled antibody by means of both cell combine analysis and LDH cytotoxicity detection kit;(3)Evaluate the injury rate of tumor exposed to 131I-chimeric anti-CD20 monoclonal antibody in vitro. The MTT method and the experiment of cell growth control are used;(4)Record the apotosis of Daudi cell using gelose electrophoresis;(5)Learn the inhibition effect of radioactive medication on the marrow. Radiohnmunoimages are taken on various intervals after injection of the labeled antibodies to the nude mice. The distribution of radioactive medication, I31l-labeled antibodies, in the marrow tissue indicates the inhibition effect. Here a B cell non-hodgkin lymphoma model in nude mice is established by us;(6)28-day observation are done in 3 groups of nude mice model.
