Immunogen
An amino acid sequence from the C-terminus of mouse PRDX3 (TIKPSPTASKEYFEKVHQ) was used as the immunogen for this Peroxiredoxin 3 antibody (100% rat homology).
The stated application concentrations are suggested starting amounts. Titration of the Peroxiredoxin 3 antibody may be required due to differences in protocols and secondary/substrate sensitivity.\. Western blot: 0.5-1 μg/mL,IHC (Paraffin): 0.5-1 μg/mL

Peroxiredoxin 3, also known as AOP-1, MER5, SP-22 or PRX3, is localized exclusively in mitochondria. The deduced 256-amino acid human protein shares 86 % amino acid sequence similarity with the mouse protein, and significant similarity with both the human proliferation-associated gene A product and the mouse stress-induced peritoneal macrophage protein Msp23. The PRDX3 gene is mapped on 10q26.11. Expression of PRDX3 is induced by MYC and is reduced in c-myc -/- cells. Chromatin immunoprecipitation analysis spanning the entire PRDX3 genomic sequence revealed that MYC binds preferentially to a 930-bp region surrounding exon 1. Results using mitochondria-specific fluorescent probes demonstrated that PRDX3 is essential for maintaining mitochondrial mass and membrane potential in transformed rat and human cells. These data provided evidence that Peroxiredoxin 3 is a MYC target gene that is required to maintain normal mitochondrial function.
