bromomaleimide-mediated bioconjugates which are either stable or cleavable in an aqueous, thiol-mediated reducing environment. The application of this methodology to reversible protein biotinylation, the irreversible labeling of peptide disulfide bonds and the assembly of stable, fluorescein-labelled glycoprotein mimics is described.
控制马来酰亚胺水解允许溴马来酰亚胺介导的生物缀合物的模块化构建,该生物缀合物在水性、硫醇介导的还原环境中稳定或可裂解。描述了这种方法在可逆蛋白质生物素化、肽二硫键的不可逆标记和稳定、荧光素标记的糖蛋白模拟物的组装中的应用。
