A one vial method for labeling a protein, such as an antibody or antibody fragment, with a radiometal such as Tc-99m or a rhenium isotope, is disclosed. The method comprises contacting in a single vial a mixture comprised of a reducing agent and a protein molecule covalently bound to a sulfhydryl containing bifunctional coupling agent with Tc or Re in an oxidized state. A one vial kit for labeling a protein with Tc or Re is also disclosed.
揭示了一种用于将蛋白质(例如抗体或抗体片段)与放射性金属(如Tc-99m或一种锇同位素)标记的一瓶法。该方法包括在单个小瓶中接触含有还原剂和与含巯基双官能偶联剂共价结合的蛋白质分子的混合物与氧化态的Tc或Re。还揭示了一种用于将蛋白质与Tc或Re标记的一瓶试剂盒。
