Redox Markers for Biosensing and Electro-active Labeling

Redox Markers

Emp BIOTECH’s Redox Markers are high-purity dyes used for covalent or passive labeling of biomolecules in biosensing and redox-based detection systems. Choose from three redox-active classes—Phenothiazines, Metal Complexes, and Quinones—to enable electron transfer-based signal generation in electrochemical assays.

Available in both non-activated and NHS-ester formats, these dyes offer flexibility for labeling proteins, oligonucleotides, and other amine- or thiol-containing molecules.

Available Redox Marker Classes:

Phenothiazine – Methylene blue derivatives for stable redox cycling
Metal Complex – Ferrocene-based markers for robust electrochemical signals
Quinone – Anthraquinone dyes for biosensors and aptamer platforms

Redox Marker Classes: Phenothiazine, Metal Complex, Quinone
