|Homo sapiens catalase (CAT)|
|Human catalase is an heme-containing peroxisomal enzyme that breaks down hydrogen peroxide to water and oxygen; it is implicated in ethanol metabolism, inflammation, apoptosis, aging and cancer. The 1. 5 A resolution human enzyme structure, both with and without bound NADPH, establishes the conserved features of mammalian catalase fold and assembly, implicates Tyr370 as the tyrosine radical, suggests the structural basis for redox-sensitive binding of cognate mRNA via the catalase NADPH binding site, and identifies an unexpectedly substantial number of water-mediated domain contacts (1). Because catalase has a low affinity for H2O2, it has been suggested that glutathione peroxidase clears most H2O2 within the erythrocyte and that catalase is of little import. It has been hypothesized that erythrocyte catalase might function to protect heterologous somatic cells against challenge by high levels of exogenous H2O2 (e.g., in areas of inflammation) (2). |

Western blot - Catalase antibody [EP1929Y]; Anti-Catalase antibody [EP1929Y] at 1/20000 dilution + HeLa cell lysate at 10 µg.Secondary.HRP labelled goat anti-rabbit at 1/2000 dilution.Predicted band size : 60 kDa.Observed band size : 60 kDa.
Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Catalase antibody [EP1929Y]; Immunohistochemical staining of Catalase in paraffin embedded human normal brain tissue using ab76024 at a 1/100 dilution.
Flow Cytometry - Anti-Catalase antibody [EP1929Y]; Overlay histogram showing HeLa cells stained with ab76024 (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 followed by the antibody for 30 min at 22°C. The secondary antibody used was Alexa Fluor? 488 goat anti-rabbit IgG (H&L) at 1/2000 dilution for 30 min at 22°C. Isotype control antibody (black line) was rabbit IgG (monoclonal) (1µg/1x10^6 cells) used under the same conditions. Unlabelled sample (blue line) was also used as a control. Acquisition of >5,000 events were collected using a 20mW Argon ion laser (488nm) and 525/30 bandpass filter.
