Product Overview
This rabbit polyclonal antibody recognizes peroxiredoxin-4 (gene PRDX4) in human, mouse and rat samples and is validated for flow cytometry, ICC/IF, IHC and Western blot. The predicted molecular weight is 30.5 kDa, and the supplier reports an observed band at about 28–30 kDa.
Peroxiredoxin 4 (PRDX4) is a secreted and endoplasmic reticulum-resident thiol peroxidase that detoxifies hydrogen peroxide. In the ER it helps couple peroxide removal to oxidative protein folding, and in the cytosol it has been reported to influence NF-κB activation through IκBα phosphorylation, so it is studied in ER stress and inflammation.

Immunogen
Synthetic peptide from the C-terminal region of human peroxiredoxin 4. It differs from the mouse and rat sequences at one residue.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places peroxiredoxin-4 in the cytoplasm and endoplasmic reticulum. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
