Malondialdehyde (MDA)

Malondialdehyde (MDA) is a natural product formed in all mammalian cells either as a product of lipid peroxidation, or as a by-product of prostaglandin and thromboxane biosynthesis. Although MDA can be broken down by aldehyde dehydrogenases, its production is accelerated by oxidative stress and when its concentrations reach critical levels, it may escape this detoxification process. It is highly reactive and known to bind covalently with primary amino groups of proteins, phospholipids, or DNA, but has no known physiological function. This covalence modification of cellular molecules may cause structural modifications, which results in dysfunction or inactivation. MDA is toxic and has been implicated in aging, mutagenesis, carcinogenesis, radiation damage and a number of other pathological processes.\n\nMDA is known to increase in tissue and plasma samples with age. It is known to bind to low density lipoprotein resulting in the recognition of the MDA-modified LDL by scavenger receptors on macrophages. It has also been shown to be present in renal glomerular lesions in diabetics, implicating oxidative stress as being involved in the pathogenesis of diabetic nephopathy. MDA has been shown to be increased in the brains of aged individuals and further increased in Alzheimer brains.\n\nApplications:\nSuitable for use in Western Blot. Other applications not tested.\n\nRecommended Dilution:\nWestern Blot: 1:3000\nOptimal dilutions to be determined by the researcher.\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
