Immunostaining of peroxiredoxins (Prx) in various cell types
| Cytoplasm | Nuclei | Cell membranes | Adjacent T-cells | |
|---|---|---|---|---|
| Prx I | 100% of samples positive expression; in 1–5% of samples granular expression | 1–5% of samples positive | Negative | 5–10% of samples cytoplasmic positivity |
| Prx II | 95% of samples positive expression | 10–20% of samples positive | 10–15% of samples positive | 10–20% of samples cytoplasmic and nuclear positivity |
| Prx III | 100% of samples granular positivity | Negative | Negative | 10–20% of samples cytoplasmic positivity |
| Prx V | 90–95% of samples positive | 10–20% of samples positive | 10–20% of samples positive | 10–20% of samples cytoplasmic and nuclear positivity |
| Prx VI | 100% of samples positive | 5–10% of samples positive | 50–60% of samples positive | 100% of samples partially positive in cytoplasm |
