PRDX3 Polyclonal Antibody

Product Specific Information

PA3-752 detects Peroxiredoxin 3 protein in human samples. This antibody is specific for Prx 3 and shows no cross-reactivity with other Prx isoforms.

PA3-752 has successfully been used in Western blot, and immunocytochemistry procedures. By Western blot, this antibody detects an ~27 kDa protein representing Prx 3 in human PC3 cell lysate.

The PA3-752 antigen is purified human recombinant Prx 3 from HEK 293 cells.

Target Information

Peroxiredoxin (Prx) is a growing peroxidase family, whose mammalian members have been known to connect with cell proliferation, differentiation, and apoptosis. Many isoforms (about 50 proteins), collected in accordance to the amino acid sequence homology, containing active site cysteine residue, and the thiol-specific antioxidant activity, distribute throughout all the kingdoms. Among them, mammalian Prx consists of 6 different members grouped into typical 2-Cys, atypical 2-Cys Prx, and 1-Cys Prx. Except Prx VI belonging to 1-Cys Prx subgroup, the other five 2-Cys Prx isotypes have the thioredoxin-dependent peroxidase (TPx) activity utilizing thioredoxin, thioredoxin reductase, and NADPH as a reducing system. Mammalian Prxs are 20-30 kilodalton in molecular size and vary in subcellular localization: Prx I, II, and VI in cytosol, Prx III in mitochondria, Prx IV in ER and secretion, Prx V showing complicated distribution including peroxisome, mitochondria and cytosol.
