Preparation and identification of ~(131)I-RP215 McAb molecular probe and its application for radioimmunoimaging in lung adenocarcinoma-bearing nude mice
ObjectiveTo prepare a targeted probe for nuclide labelingmonoclonal antibody(McAb)against carbohydrate-associated antigen,carbohydrate antigen 215(CA215)which are expressed on the surface of lung adenocarcinoma cells,identify the physico-chemical properties of the probe,and to explore its distribution in vivo and radioimmunoimaging(RⅡ)characteristics in tumor-bearing nude mice model.Methods McAb RP215 was labeledby the chloramine T method,and then the products were purified with the Sephadex G25M column.The...
