Redox Markers for Biosensing and Electro-active Labeling
Quinone Redox Markers for Biosensing and Bioconjugation
Anthraquinone-based redox markers provide stable and well-defined redox behavior, ideal for electron-transfer studies and biosensor integration. Available as non-activated acids or amine-reactive NHS esters, these quinone dyes—offered with or without extended C6 linkers—enable flexible covalent labeling of proteins, peptides, or oligonucleotides for redox-based detection assays.
Other Redox Marker classes available :
Phenothiazine – Methylene blue derivatives for stable redox cycling
Metal Complex – Ferrocene-based markers for robust electrochemical signals
