Detection of Human Peroxiredoxin 1 by Western Blot. Western blot shows lysates of Raji human Burkitt's lymphoma cell line, A431 human epithelial carcinoma cell line, and MCF‑7 human breast cancer cell line. PVDF membrane was probed with 0.1 µg/mL of Human Peroxiredoxin 1 Monoclonal Antibody (Catalog # MAB3488) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for Peroxiredoxin 1 at approximately 22 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: Peroxiredoxin 1
Human Peroxiredoxin1 (Prx-1, also known as Thioredoxin peroxidase 2) is a 22 kDa antioxidant enzyme that belongs to the typical 2-Cys class of the THP/ahpC family of proteins. The molecule is 199 amino acids (aa) in length and has two catalytic cysteines, one at Cys52 and a second at Cys173. Prx-1 is an obligate homodimer. In its inactive state, Prx-1 is apparently noncovalently associated. Upon peroxide binding to Cys52 of subunit 1, the Cys173 of subunit 2 interacts with Cys52 of subunit 1 to complete the antioxidation, generating a disulfide bond between Cys52 and Cys173. Subsequent reduction restores the subunits to the basal state. There are apparently two additional isoforms; one shows a premature truncation after aa 171, while the second shows a deletion of aa 21‑121. Human Prx-1 is 96% aa identical to mouse Prx-1.
