Novel biotin analogues, such as 2-Azidobiotin, comprising the ureido ring of natural biotin with the thiophene ring, optionally modified, and a modified sidechain having a functional end group, preferably selected from the group consisting of a carboxylic acid, amine, alcohol, thiol, aldehyde and a halide, and at least one bio-orthogonally reactive chemical group located elsewhere in the sidechain. The analogues are used for labelling target structures and biomolecules, such as peptides and proteins in vitro or in vivo.
新型生物素类似物,例如2-叠氮基生物素,包括天然生物素的尿素环和噻吩环,可选择性地改性,以及具有功能末端基团的改性侧链,优选从羧酸、胺、醇、硫醇、醛和卤素组成的群中选择,并且在侧链的其他位置至少有一个生物正交反应化学基团。这些类似物用于在体内或体外标记靶结构和生物分子,例如肽和蛋白质。
