Reagents are disclosed for chemoselective tagging of methionine residues in peptides and polypeptides, subsequent bioorthogonal tag functionalization, and cleavage of the tags when desired to regenerate unmodified samples. This method compliments other peptide tagging strategies and adds capability for tag removal, which may be useful for release of therapeutic peptides from a carrier, or release of tagged protein digests from solid supports.
本文披露了一种针对肽和多肽中蛋氨酸残基的化学选择性标记试剂,随后进行生物正交标记功能化,并在需要时剥离标记以再生未修饰样品的方法。该方法补充了其他肽标记策略,并增加了标记去除的能力,这可能对于从载体中释放治疗性肽或从固体支持中释放标记蛋白消化物是有用的。
