A radiolabeling method for bioconjugation based on the DielsâAlder reaction between 3,6-diaryl-s-tetrazines and an 18F-labeled trans-cyclooctene is described. The reaction proceeds with exceptionally fast rates, making it an effective conjugation method within seconds at low micromolar concentrations.
本文描述了一种基于3,6-二芳基-s-四嗪与18F标记的反式环辛烯之间的狄尔斯-阿尔德反应的放射性标记生物偶联方法。该反应在微摩尔浓度下能在几秒钟内以极快的速率进行,是一种高效的偶联方法。
