Product Description
 
Product: Catalase, Human Erythrocyte
Catalog Number: HEC
Product Page: http://www.mol-innov.com/products/catalase-human-erythrocyte
Description: Composed of four identical subunits each with a molecular weight of 58,000. Catalyzes the reaction 2H2O2 to H2O+O2. Catalase, along with the superoxides dismutase and glutathione peroxidase, controls the levels of oxygen-derived free radicals in mammalian cells, and together may function as a somatic oxidant defense. Prepared from whole blood shown to be non reactive for HbsAG, anti-HCV, anti-HBc, and negative for anti-HIV 1 & 2 by FDA approved tests. >95percent pure by SDS-PAGE.
Recommended Storage: -70 C
Shipping Conditions: Dry ice
Minimum Shelf Life: 3 years from delivery
