Linoleic acid peroxidation assay
NettetNational Center for Biotechnology Information NettetThe kit employs an alkynyl linoleic acid analogue that is incorporated into cellular lipid membranes and is subject to peroxidation by various exogenous ROS or pro-oxidant treatments, followed by a click chemistry labeling reaction with an azide-containing dye.
