抗坏血酸(Ascorbic Acid,AsA)作为植物细胞一个重要生理指标,其含量、氧化还原状态(AsA/DHA比率)以及合成与代谢相关酶类活性的变化,涉及植物对一系列环境胁迫的响应。脱氢抗坏血酸(DHA)是AsA的可逆氧化形态,在生物体内与抗坏血酸共同构成氧化还原系统,起到电子受体的作用。本试剂盒检测原理是还原剂二硫苏糖醇(DTT)特异性地将样本中待测的DHA 完全还原为AsA,通过测定体系中 AsA 的生成速率,即可计算出 DHA 含量。
Ascorbic acid (AsA) serves as a key physiological indicator in plant cells. Changes in its content, redox status (AsA/DHA ratio), and the activities of enzymes involved in its synthesis and metabolism are associated with plant responses to a range of environmental stresses. Dehydroascorbic acid (DHA) is the reversibly oxidized form of AsA and, together with ascorbic acid, constitutes a redox system in organisms, functioning as an electron acceptor. The detection principle of this kit is based on the specific and complete reduction of DHA in the sample to AsA by the reductant dithiothreitol (DTT). The DHA content is then calculated by measuring the rate of AsA generation in the system.
