article Installing a Redox Switch on Biomolecules: Principles, Conjugation Essentials, and an Application Guide for ATTO MB2 NHS ester ATTO MB2 NHS ester can be understood as a covalently attachable “active tag” made by converting the classic redox dye methylene blue (MB) into an NHS ester that reacts with primary amines on biomolecules. 更新于 2026年1月阅读12分钟
article 把生物分子装上红氧开关:ATTO MB2 NHS ester 的原理、偶联要点与应用导航 ATTO MB2 NHS ester 可以理解为:把经典红氧染料亚甲蓝(Methylene Blue)做成可与生物分子共价偶联的活性标签(NHS 酯与一级胺反应)。它的亮点不在“更花哨的颜色”,而在于可逆红氧开关:氧化态在~668 nm 具有强吸收,被还原后转为几乎无色的 ... 更新于 2026年1月阅读12分钟
