English name: ASO; Ascorbate Oxidase from Cucurbita sp; L-Ascorbate: oxygen oxidoreductase; Ascorbase
CAS number: 9029-44-1
Level: Refined level Vitality: 1000 ～ 3000 units / mg protein
Definition of vitality: One unit will oxidize 1.0 μmole of L-ascorbate to dehydroascorbate per min at pH 5.6 at 25 ℃
Protein: ～ 10% Lowry
Properties: white or almost white or slightly copper-blue crystalline powder. It belongs to the ceruloplasmin family, with a molecular weight of 140kD and is composed of two identical subunits (70kD). It is an oxidoreductase. Catalyze the action of ascorbic acid and oxygen to produce dehydroascorbic acid. Ascorbic acid is an unsaturated polyhydroxy compound that exists in the form of a lactone. The hydrogen on the enol hydroxyl group between the 2 and 3 carbon atoms can be free to form H +, so it has an acidic purpose: biochemical research. Elimination of Ascorbate. A strong reducing agent is oxidatively dehydrogenated to dehydroascorbic acid, so there are two types of oxidized and reduced types.
Storage: 2 ～ 8 ℃, shelf life is 2 years
