9003-99-0 Usage


Peroxidase is a diverse group of oxidoreductases enzymes that use peroxide as an electron acceptor. They have a wide substrate spectrum, including hydrogen peroxide, phenolic compounds, and recalcitrant dyes. Peroxidases are naturally occurring in various sources, including milk (lactoperoxidase) and horseradish.


Used in Food Industry:
Peroxidase is used as a stabilizing ingredient to help improve formulation stability and product shelf-life. It is naturally occurring in milk and can be directly supplemented to food for the degradation of carotenoids used for coloring cheese.
Used in Wastewater Treatment:
Peroxidases, particularly DyP-type peroxidases, are used for the degradation of recalcitrant dyes in wastewater treatment. A fungal peroxidase of the DyP-type, MaxiBright (DSM), has been commercialized for bleaching whey fluid resulting from colored cheese production.
Used in Molecular Biology:
Peroxidase from horseradish is used in the oxidation of luminol to 3-aminophthalate. It is often used in conjugates to determine the presence of a molecular target, especially in the detection of specific proteins in a western blot after conjugation with an antibody.
Used in Cancer Research:
Peroxidase from horseradish is highly reactive toward human tumor cells, making it a valuable tool in cancer research and potential therapeutic applications.

Check Digit Verification of cas no

The CAS Registry Mumber 9003-99-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,0 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 9003-99:
90 % 10 = 0
So 9003-99-0 is a valid CAS Registry Number.
