General description

Catalase is one of the most efficient and common enzyme found in nearly all living organisms exposed to oxygen. It is a very important enzyme in protecting the cell from oxidative damage by reactive oxygen species (ROS). In most mammalian cell types catalase is localized in peroxisomes which is a tertrameric haemin-enzyme consisting of 4 identical tetrahedrally arranged subunits of 60kDa. It contains four ferriprotoporphyrin groups per molecule having a molecular mass of 240kDa.

Application

Applications in which this antibody has been used successfully, and the associated peer-reviewed papers, are given below.
Western Blotting (5 papers)
Monoclonal Anti-Catalase antibody produced in mouse is suitable for the following:
  • Immunocytochemistry
  • Immunohistochemistry
  • Indirect ELISA
  • Microarray
  • Western blotting at a concentration of 0.5-1μg/mL using whole extract of HepG2 cells
  • Immunofluorescence

Biochem/physiol Actions

Catalase reacts with hydrogen peroxide, a reactive oxygen species, activating its decomposition into water and molecular oxygen and it reacts with hydrogen donors. It functions as a natural anti-oxidant, protecting cells against oxidative damage of proteins, lipids and nucleic acids. Catalase also plays a role in gene expression and apoptosis. Antioxidants have been identified in association with a variety of diverse cellular functions including growth control, proliferation, differentiation, immune response, tumor promotion, apoptosis and activation of viruses.

Physical form

Solution in 0.01 M phosphate buffered saline, pH7.4, containing 15 mM sodium azide

Preparation Note

Purified from culture supernatant of hybridoma cells grown in a bioreactor.

Evidence is growing that reactive oxygen species (ROS), by-products of (normal) cellular aerobic metabolism, are involved in the pathogenesis of neurodegenerative diseases. One of these diseases is amyotrophic lateral sclerosis (ALS), in which motoneurons die, leading to paralysis and death.

Hydrogen peroxide (H2O2) is a reactive oxygen species that at low concentration is toxic to sperm. H2O2 inhibits not only sperm viability but also the acrosome reaction, sperm-egg binding, and oocyte penetration. Catalase activates the decomposition of H2O2 into water
