EnzChek™ Myeloperoxidase (MPO) Activity Assay Kit - FAQs

The EnzChek Myeloperoixdase Activity Assay Kit (Cat. No. E33856) can detect myeloperoxidase activity at a broad dynamic range of 1.5 to 200 ng/mL.

MPO is inhibited by azide, diclofenac, methimazole, quercetin, rutin, and salicylhydroxamic acid. Make certain that samples do not include sodium azide. Endogenous catalases can interfere with the assay; catalase activity may be inhibited by using 3-amino-1,2,4-triazole. Detergents, common components in cell lysis buffers, should be avoided; use freeze/thawing and/or mechanical methods to lyse cells.
