Oxidative Stress Analysis

ROS detection kits and antioxidant capacity assays for reliable oxidative stress data

Oxidative stress research often means juggling separate kits for ROS detection, antioxidant capacity, and damage markers, and these kits work directly in your live cells, lysates, plasma, or tissue, without specialist equipment. The range covers hydrogen peroxide and superoxide detection, antioxidant enzyme activity for superoxide dismutase, catalase, and glutathione peroxidase, total antioxidant capacity assays such as FRAP and TAC, lipid peroxidation kits measuring MDA and 4-HNE, and transcription factor activation profiling for oxidative stress signalling. Direct ROS detection with fluorescent probes such as DCFH-DA reports on reactive oxygen species in live cells but gives a non-specific, cumulative signal, so it is best treated as a semi-quantitative readout rather than an absolute measure of a single ROS species. Oxidative damage markers such as MDA/TBARS or 4-HNE are stable downstream products of lipid peroxidation, giving an integrated endpoint you can measure in lysates, plasma, or urine at any time after the stress event.
