Description: Peroxiredoxin-3 is a ubiquitous, 22-28kD mitochondrial antioxidant enzyme that belongs to the 2-Cys class of the TSA/ahpC family of peroxiredoxins. Prx-3 is known to act as either a homodimer, or a decamer, and scavenge reactive oxygen species generated by oxidative stress. The mouse Prx-3 precursor molecule is 257aa in length. It contains a cleavable N-terminal 63aa mitochondrial targeting sequence, plus a 194aa mature enzyme that shows a thioredoxin domain between aa64-222. There are two catalytic cysteines, one at Cys109 and another at Cys230 of the precursor. Prx-3 undergoes a phosphorylation at Thr147 that reduces its activity. One potential splice form shows a deletion of Arg149, Lys150 and Arg185. Full-length mouse Prx-3 is 86-95aa identical to human and rat Prx-3, respectively. Applications: Suitable for use in Western Blot. Other applications not tested. Recommended Dilution: Western Blot: 1ug/ml Optimal dilutions to be determined by the researcher. Storage and Stability: Lyophilized powder may be stored at -20°C. Stable for 12 months at -20°C. Reconstitute with PBS. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Reconstituted product is stable for 12 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer. |
