DHN-MA Lipid Peroxidation EIA kit

Enzyme ImmunoAssay (EIA) is a technique to detect and quantify antigens (proteins, hormones.) or antibodies in samples. It relies on the ability of an antibody to bind a specific antigen. Either the antibody or the antigen is labelled with an enzyme whose substrate is a chromogen or a fluorogen converted in a measurable product (color or fluorescence)., Enzyme-linked Immunosorbent Assay (ELISA) is a type of EIA using a solid phase (ex: microtiter plate) coated with an antigen immobilizing the molecule to detect. Over the time, scientists have extended the term ELISA to EIAs using an antibody coating the solid phase. That explains why our EIA kits using coated antibodies are also called ELISA kits., Lipid peroxidation is a well-established mechanism of cellular injury in both plants and animals and is used as an indicator of oxidative stress in cells and tissues., Measurement of 4-hydroxy-2-nonenal (HNE), an aldehyde formed during the lipid peroxidation process, is one of several accepted biomarkers for lipid peroxidation. 1,4-Dihydroxynonane mercapturic acid (DHN-MA) is the major urinary metabolite of HNE present at physiological levels in rat and human urine. It can be measured without extraction and offers an alternative lipid peroxidation biomarker aside from 8-isoprostane or TBARS. This DHN-MA EIA Kit is a competitive assay that can be used for quantification of DHN-MA in urine samples. The EIA typically displays an IC50 (50% B/B0) of approximately 75 pg/ml and a detection limit (80% B/B0) of approximately 10 pg/ml.
