Hexanoyl-Lysine  ELISA
(ELISA kit for 13-HPODE Lysine adduct)
Catalog #KHL-700E

Product Insert (pdf)


Oxidative damage of lipids caused by reactive oxygen species (ROS) plays an important role in the lesion of cell functions and aging. Aldehydes such as malondialdehyde (MDA) and 4-hydroxy-2-nonenal (4-HNE) have been reported as the advanced lipid peroxidation products. In the earlier stages of lipid peroxidation, 13-hydroperoxyoctadecanoic acid (13-HPODE) is found to be covalently bound to proteins1). Hexanoyl-Lysine adduct  is a novel lipid hydroperoxide-modified lysine residue. It  is formed by oxidative modification by oxidized omega-6 fatty acids such as linoleic acid or arachidonic acid.  Using this kit, Hexanoyl-Lysine can be measured in human urine and serum.
