title: Generation and characterization of IgG monoclonal antibodies specific for malondialdehyde.
abstract: Numerous studies have indicated that the oxidative modification of low-density lipoprotein (LDL) plays a critical role in the pathogenesis of atherosclerosis. Malondialdehyde-modified LDL (MDA-LDL) is one of the candidate oxidative products. Therefore, to allow the assessment of oxidized LDL in human serum, we developed monoclonal antibodies for MDA-LDL. Two of these-MDA1 and MDA2-bound to oxidized LDL but not to native LDL by Western blot analysis. The murine monoclonal antibodies to oxidized LDL have potential clinical implications, as imaging agents, for defining the compositions of atherosclerotic vessels in vivo.
