lipid peroxide analysis by liquid phase colorimetry thiobarbituric acid assay 2014-03-11T17:18:02Z JSmith MMO:0000513 Method of assessing the amount one or more end products of lipid peroxidation, the oxidative degradation of lipids, in a solution using an assay in which thiobarbituric acid is heated with a tissue or biological fluid sample at an acidic pH to produce a red chromogen. The level of TBA-reactive substances in the sample is determined by spectrophotometric analysis of absorbtion at ~532 nm or fluorescence at 553 nm.
