Immunoassays for Lipid Peroxidation End Products: One-Hour ELISA for Protein-Bound Acrolein and HNE
Time of Update: 2020-11-30
An alternative approach is the immunochemical quantification of reaction products accumulating in vivo, for which monoclonal antibodies (MAbs) specific for the acrolein-modified lysine and 4-hydroxy-2-nonenal (HNE)-modified histidine epitopes have been prepared (Fig. 1 ) ( 6 , 7 ).
