Monocarboxymethylene blue succinimidyl ester; Monocarboxymethylene blue NHS ester; Methylene blue NHS ester; Methylene blue succinimidyl ester
NHS ester, reacts with 1° amines to form a stable amide linkage
The amine-reactive methylene blue derivative is used as an electroactive labeling reagent for covalent attachment to proteins and alkylamino modified nucleic acids. Monocarboxymethylene blue contains a single activated carboxylic acid functional group. In addition to its relatively high absorption, MCMB, has excellent and validated redox properties and is a good generator for singlet oxygen, making it to a particularly suitable label for electrochemical and photosensitzer applications.
