Purification notesab34634 was purified from monospecific antiserum by a multistep process which includes delipidation, salt fractionation and ion exchange chromatography followed by extensive dialysis against the buffer stated above. Assay by immunoelectrophoresis resulted in a single precipitin arc against anti-Biotin, anti-Sheep Serum as well as purified and partially purified Lactoperoxidase (Bovine Milk).
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use at an assay dependent concentration.
RelevanceLactoperoxidase is a natural antibacterial agent in bovine milk, a medium otherwise rich in its ability to support bacterial growth. Milk lactoperoxidase levels vary among species, ranging from little or none in humans to very high concentrations in guinea pigs. Interestingly, lactoperoxidase from milk is identical to the lacrimal and salivary forms of the enzyme. In addition, the enzyme catalyzes the hydrogen peroxide oxidation of iodine and can be employed in labelling proteins with radioiodine.
