Oxford Biomedical Research has recently redesigned its FR40 TBARS assay to increase sensitivity and reduce interferences.  We have also introduced a fluorometric TBARS assay with exceptional sensitivity.  These kits have the best sensitivity and the least interference of all kits commercially available.  While all TBARS assays detect endogenous interfering factors, many more are generated when samples are boiled with strong acid.  Their new, patent pending method uses a milder acid and can be run at room temperature.
