Extra Details:: Lactoperoxidase is a peroxidase enzyme found in milk. It is able to form reactive bromine and iodine species, resulting in natural organobromine and organoiodine substances, and can therefore be categorised as a haloperoxidase. It is fairly heat resistant and was widely used as an indicator of overpasteurization of milk.Freshly isolated and purified samples of goat LPO were saturated with ammonium iodide and crystallized using 20% polyethylene glycol 3350 in a hanging drop vapor diffusion setup. Goat LPO consists of a single polypeptide chain of 595aa residues and folds into an oval-shaped structure. The structure contains 20 well-defined alpha-helices of varying lengths including a helix, H(2a), unique to LPO, and two short antiparallel beta-strands. Applications: Suitable for use in ELISA, Western Blot, Immunohistochemistry, Immunocytochemistry. Other applications not tested. Recommended Dilution: ELISA: 1:100-5000 Western Blot: 1:50-400 Immunohistochemistry (frozen): 1:50-500 Immunohistochemistry (paraffin): 1:10-100 Immunocytochemistry: 1:50-500 Optimal dilutions to be determined by the researcher.
