186Re标记博莱霉素的研究
A Study on  ̄(186)Re labelling of bleomycin
【摘要】 采用Sn(Ⅱ)还原法,系统研究了反应条件对186Re-BLM形成的影响.结果表明:pH值对络合物产额影响最大.以葡萄糖酸钠为保护剂,可避免反应过程中铼的重新氧化,并建立了pH3—4.5时产额达98%的制备条件.
【Abstract】 The influence of several factors on 186Re-BLM formation is investigated by means of Sn(II) reducing method. The results show that the labelling yield is mainly dependent on the pH value in reaction medium, and that sodium gluconate is a suitable protecting agent to avoid Re-oxidation of the reduced Re. The method for preparing 186-BLM is described with labelling yield up to 98% in the pH range from 3 to 4.5.
