The superiority of radiopharmaceutical compare to the other techniques of medical services, especially for diagnosis and therapy of several deadly diseases such as cancer or diagnosis of infection and iflammmation . Infection diseases are common in Indonesia, Nuclear medicine techniques which uses polyclonal antibody based radiopharmaceutical labeled with technetium-99m offers an alternative method of diagnosis infection/inflammation. Preparation of 99mTc- Immunoglobulin M(99mTc_IgM) and its analysis have been carried out. This preparation needs several steps, first reducing IgM using mercaptoetanol with molar ratio 1:2000-12000, purification using PO-IO column ( sephadex G-25,Pharmacia), and the reduced IgM was labeled with 99mTcand MDP as transchelator. The reduced IgM was analysed using size exlusion_HPLC The radiochemical purity of 99mTc_IgM was analysed using TLC/paper chromatography. The stability in the human body was carried out by using fresh human serum after 1 and 2 hours incubation, Biodistribution test on infected mice was carried out, the radiochemical purity of 99mTc_IgM analysed with TLC/paper chromatography was higher than 90 % for molar ratio Ab:Me 1:12000. The stability of labeled IgM in fresh human serum was stable after 1 and 2 hours incubation, biodistribution test showed higher uptake in the site of infection ( right thigh) compare to the site of uninfection ( left thigh).
