RelevancePeroxiredoxin (Prx) is a growing peroxidase family whose mammalian members are involved in cell proliferation, differentiation, and apoptosis. There are many isoforms(about 50 proteins), known on the basis of amino acid sequence homology, particularly the amino-terminal region containing an active site cysteine residue. The thiol-specific antioxidant activity is distributed 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 PrxVI belonging to the 1 Cys Prx subgroup, the other five 2 Cys Prx isotypes share the thioredoxin dependent peroxidase(TPx) activity utilizing thioredoxin, thioredoxin reductase, and NADPH as a reducing system. Mammalian Prxs are 20–30 kilodaltons in molecular size and vary in subcellular localization:PrxI, II and VI in cytosol, PrxIII in mitochondria, PrxIV in ER and secretion, PrxV showing complicated distribution including peroxisome, mitochondria and cytosol.

ICC/IF image of ab16765 stained HCT116 cells. The cells were 100% methanol fixed (5 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab16765, 10µg/ml) overnight at +4°C. The secondary antibody (green) was ab96879, DyLight® 488 goat anti-mouse IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM

Overlay histogram showing HeLa cells stained with ab16765 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab16765, 1µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells ) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive signal in HeLa cells fixed with 4% paraformaldehyde (10 min)/permeabilized in 0.1% PBS-Tween used under the same conditions.
