Description

Peroxidase CAS NO 9003-99-0 is a vital enzyme that catalyzes the oxidation of various organic and inorganic substrates using hydrogen peroxide as an electron acceptor. This catalytic activity is fundamental to numerous industrial, diagnostic, and research processes requiring controlled oxidation or signal generation. It is an essential reagent for manufacturers and researchers in the biotechnology, clinical diagnostics, food processing, and environmental monitoring sectors.

Application

• Clinical Diagnostics & ELISA Kits: Widely used as a key enzyme conjugate for signal amplification in immunoassays, including ELISA, Western blotting, and immunohistochemistry.
• Biosensor Development: Employed as a biological recognition element in amperometric and optical biosensors for detecting hydrogen peroxide, glucose, cholesterol, and other analytes.
• Food Industry: Utilized in enzymatic assays for food quality control, such as the detection of glucose or as a processing aid in certain baking applications.
• Biotechnology Research: A critical tool in molecular biology for blotting techniques, DNA detection systems, and studying oxidative stress pathways.
• Environmental Monitoring: Incorporated into test kits and probes for the detection of phenolic compounds and peroxides in water and soil samples.
• Pharmaceutical R&D: Used in drug discovery for high-throughput screening assays involving oxidative reactions and as a model enzyme in biochemical studies.

Quality Control

Our Peroxidase is produced and tested under stringent quality management systems to ensure batch-to-batch consistency and high catalytic activity. Each lot is characterized for key parameters including RZ value (Reinheitszahl or purity number), specific activity, and stability. Certificates of Analysis (COA) detailing these specifications are provided with every shipment to guarantee compliance with your application requirements.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store lyophilized powder at 2-8°C. Reconstituted enzyme solutions should be aliquoted and stored at -20°C or below to prevent activity loss. Avoid repeated freeze-thaw cycles. This product is easily oxidized; handle under appropriate conditions to maintain stability.
