Improved synthesis methods are provided for preparing conjugates of proteins and chelating agents. In the synthesis methods, non-stable bonds are hydrolyzed after the conjugate is synthesized, for example by treating the conjugate with a quenching agent. The synthesis method provides conjugates that are substantially free of non-stable bonds between the protein and the chelating agent, such that the chelating agent is less likely to dissociate with the conjugate after the conjugate has been stored for extended periods. The conjugate may be useful for therapeutic or diagnostic methods.
提供了改进的合成方法,用于制备蛋白质和螯合剂的共轭物。在合成方法中,非稳定键在共轭物合成后水解,例如通过处理共轭物来处理淬灭剂。合成方法提供了基本上没有蛋白质和螯合剂之间的非稳定键的共轭物,因此在共轭物存储了一段时间后,螯合剂不太可能与共轭物解离。共轭物可能用于治疗或诊断方法。
