Catalog Number: 25430 - Catalase, Aspergillus niger

 Introduction:Long–acting, extremely stable form of catalase that is active from pH 2–12. Composed of four protein subunits, each containing a heme (Fe3+–protoporphyrin) group bound to its active site. Each subunit also contains one molecule of bound NADPH that helps to stabilize the enzyme. Catalyzes the reaction 2H2O2¨2H2O+O 2. Catalase, along with superoxide dismutase and glutathione peroxidase, controls the level of oxygen–derived free radicals in mammalian cells, and together may function as a somatic oxidant defense. Prevents apoptosis in cultured rat ovarian follicles.  

Catalog Number: 25431 - Catalase, Bovine Liver

 Introduction:Catalase, along with superoxide dismutase and glutathione peroxidase, controls the levels of oxygen–derived free radicals in mammalian cells. Together these molecules may function as a somatic oxidant defense. Prevents apoptosis in cultured rat ovarian follicles.
 

Catalog Number: 25432 - Catalase, Human Erythrocyte

Introduction:Catalase, along with superoxide dismutase and glutathione peroxidase, controls the levels of oxygen–derived free radicals in mammalian cells. Together these molecules may function as a somatic oxidant defense. Prevents apoptosis in cultured rat ovarian follicles. 

Catalog Number: 25433 - Glutathione Reductase, Yeast

 Introduction:Catalyzes the oxidation of reduced NADPH to NADP+. Links the hexose monophosphate pathway to the glutathione pathway. 

Catalog Number: 25437 - Myeloperoxidase, Human Polymorphonuclear Leukocytes

Introduction:A lysosomal heme protein that catalyzes oxidations by hydrogen peroxide, including MPO–chloride-mediated killing of microbes and tumor cells, inactivation of  Catalog Number: 25411 - Superoxide Dismutase (SOD Cu/Zn), Bovine Liver  factors, cross–linking of proteins, and iodination of proteins
