The antibody detects endogenous human, mouse and rat Peroxiredoxin 2 in in Western blots. In Western blots, approximately 25% cross‑reactivity with recombinant human (rh) Peroxiredoxin 1 and rhPeroxiredoxin 4 is observed, approximately 10% cross-reactivity with rhPeroxiredoxin 3 is observed, and less than 1% cross‑reactivity with rhPeroxiredoxin 5 and rhPeroxiredoxin 6 is observed.
Polyclonal Goat IgG
E. coli-derived recombinant human Peroxiredoxin 2 Met1-Asn198 Accession # P32119
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied as a 0.2 µm filtered solution in PBS.
Detection of Human/Mouse/Rat Peroxiredoxin 2 by Western Blot.
Western blot shows lysates of Raji human Burkitt's lymphoma cell line, A20 mouse B cell lymphoma cell line, and NRK rat normal kidney cell line. PVDF membrane was probed with 0.2 µg/mL of Goat Anti-Human/Mouse/Rat Peroxiredoxin 2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3489) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). A specific band was detected for Peroxiredoxin 2 at approximately 24 kDa (as indicated). This experiment was conducted using Immunoblot Buffer Group 2.
Detection of Human Peroxiredoxin 2 by Simple WesternTM.
Simple Western lane view shows lysates of Raji human Burkitt's lymphoma cell line, loaded at 0.2 mg/mL. A specific band was detected for Peroxiredoxin 2 at approximately 27 kDa (as indicated) using 2 µg/mL of Goat Anti-Human/Mouse/Rat Peroxiredoxin 2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3489) followed by 1:50 dilution of HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

Background: Peroxiredoxin 2
Human peroxiredoxin-2 (Prx-2 or PRDX2; also Thioredoxin Peroxidase 1) is a 22 kDa antioxidant enzyme that belongs to the typical 2-Cys class of the THP/ahpC family of proteins. The precursor molecule is 198 amino acids (aa) in length, and has two catalytic cysteines, one at Cys50 and a second at Cys171. Prx-2 is an obligate homodimer. Inactive, it is apparently noncovalently associated. Upon peroxide binding to Cys50 of subunit 1, the Cys171 of subunit 2 interacts with Cys50 of subunit 1 to complete the antioxidation, generating a disulfide bond between Cys50 and Cys171. Subsequent reduction restores the subunits to the basal state. There are two additional isoforms. Isoform-b shows a deletion of aa 36‑86, while isoform c shows a substitution of 56 aa after residue 86. Human Prx-2 is 93% aa identical to mouse and rat Prx-2.
