Peroxiredoxin 4 Antibody [Unconjugated]

Western blot shows lysates of HeLa human cervical epithelial carcinoma cell line, HEK293 human embryonic kidney cell line, K562 human chronic myelogenous leukemia cell line, NIH-3T3 mouse embryonic fibroblast cell line, and NRK rat normal kidney cell line. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human/Mouse/Rat Peroxiredoxin 4 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5460) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). A specific band was detected for Peroxiredoxin 4 at approximately 32 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 2.

Peroxiredoxin 4 was detected in immersion fixed paraffin-embedded sections of human liver cancer tissue using Goat Anti-Human/Mouse/Rat Peroxiredoxin 4 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5460) at 0.3 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Goat IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC004). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to cancer cells.

Background

Peroxiredoxin 4 (Prx-IV; also known as PRDX4 and thioredoxin peroxidase AOE372) is a 30-32 kDa, widely expressed cytoplasmic antioxidant enzyme that belongs to the typical 2-Cys class of the TSA/ahpC family of peroxiredoxins. It exists as either a homodimer, or heterodimer with PRDX1. PRDX4 reportedly counteracts
p53‑mediated generation of ROS, and regulates NF kappa B via I kappa B-alpha . Human PRDX4 is 271 amino acids (aa) in length and contains an N-terminal poly-Leu region
(aa 20‑30) and a 159 thioredoxin domain (aa 79‑237). There is one catalytic cysteine at Cys124. Over amino acids 1‑271, human PRDX4 shares 89% aa identity with mouse and rat PRDX4.
