用途過酸化水素の定量系においてアスコルビン酸の干渉除去に用いる。
使用Ascorbate oxidase, from Cucurbita sp., may be used to study oxidative stress and heat stress response and tolerance. Also used in ascorbic acid assays to study the heat stress response of Arabidopsis and useful for enzymatic determination of ascorbic acid and for eliminating the interference of ascorbic acid in clinical analysis.
一般的な説明Ascorbate oxidase is a homodimeric enzyme, which comprises 552 amino acid residues per subunit (zucchini). It corresponds to a molecular mass of 70kDa per subunit. This enzyme is mainly found in plants, fungi and eubacteria.
