WebThe structure of catalase from human erythrocytes (HEC) was determined in tetragonal crystals of space group I4(1) by molecular-replacement methods, using the orthorhombic crystal structure as a search model. It was then refined in a unit cell of dimensions a = b = 203.6 and c = 144.6 A, yielding R and R(free) of 0.196 and 0.244, respectively ... WebCatalase is an enzyme found in all manner of organisms, including humans. Catalase does little more than catalyse the conversion of hydrogen peroxide into oxygen and water, but it does this with near-perfect efficiency, making it a very powerful antioxidant.

WebThe NeuroMab™ anti-Catalase antibody recognizes endogenous levels of total catalase protein. Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues near the carboxy terminus of human catalase protein. Store at -20°C. Do not aliquot the antibody.
Web12 Mar 2002 · Abstract. Environmental stimuli such as UV, pathogen attack, and gravity can induce rapid changes in hydrogen peroxide (H 2 O 2) levels, leading to a variety of physiological responses in plants. Catalase, which is involved in the degradation of H 2 O 2 into water and oxygen, is the major H 2 O 2 -scavenging enzyme in all aerobic organisms. ha-joon kimWebCatalase Antibodies Antibodies that detect Catalase can be used in several scientific applications, including Western Blot, Immunohistochemistry, Immunocytochemistry, Immunoprecipitation and ELISA.
