WebA regression equation is calculated from the standard horseradish peroxidase results, and the change in A 510 for each sample is substituted into the equation to find the units of POD activity. Note that peroxidase activity will be expressed on a plant protein basis (refer to ERT/SERAS SOP# 2033, "Plant Protein Determination"). WebJul 5, 2013 · Measuring myeloperoxidase activity in biological samples We validated a highly specific and sensitive assay protocol that should be used as the standard method for all MPO activity assays in biological samples. We also established a method to obtain extra- and intracellular MPO from murine organs.
