Selection Guide for Oxidative Stress Assays by Sample Type

Selecting assays for oxidative stress begins with your samples. There are many markers of oxidative stress, but some are more easily detected in certain sample types (cells, tissues, urine, blood, etc.). We have developed a broad portfolio of sensitive, easy-to-use assays to quantify oxidative stress. Use the following table to determine the best assays for your sample type.

NOTE: Many oxidative stress markers degrade over time, so the best results usually come from fresh samples. For best results from samples that have been frozen for 6 to 24 months, choose one of the markers below with an asterisk (*).
