General description

Donor:hydrogen-peroxide oxidoreductase
Peroxidase (POD) (E.C. 1.11.1.7) is extensively expressed in most fruits and vegetables.

Application

Oxidation of electron donors (e.g., epoxidation of double bonds). Peroxidase can be coupled to other proteins via its amino groups, as well as its carbohydrate moiety. The reconstituted solution can be used directly for conjugation without prior dialysis.It has been used in ligand blotting.
Peroxidase (POD) has been used in AUR (Amplex UltraRed assay) to measure extracellular H2O2 produced from disaggregated slug cells.

Biochem/physiol Actions

Peroxidase (POD) is involved in the dehydrogenation of a large number of organic compounds including, phenols and aromatic amines, hydroquinones and hydroquinoid amines, mainly benzidine derivatives.

Quality

Contaminants: <0.001% ATPase and acid phosphatase each, <0.7% catalase
Purity number: approximately 3.0 (A403/A275)

Preparation Note

Activator: Ammonia, pyridine, imidazole, all at pH >7; detergents.
Working solution: PBS (phosphate buffered saline) or water (starting concentration 20 mg/ml).

Reconstitution

Solution (10 mg/ml in water): clear, red brown; pH-value: 6.0 to 7.0.

Extracellular traps (ETs) from neutrophils are reticulated nets of DNA decorated with anti-microbial granules, and are capable of trapping and killing extracellular pathogens. Various phagocytes of mammals and invertebrates produce ETs, however, the evolutionary history of this DNA-based host defence
