More Details

  • Ascorbic acid (the L-enantiomer commonly known as vitamin C) is an important antioxidant found in living organisms and applied as additives in food and other industrial processes. By reacting with reactive oxygen species, it protects the cell from oxidative damages. BioAssay Systems method provides a simple, direct and high-throughput assay for measuring ascorbic acid. In this assay, ascorbic acid is oxidized by ascorbate oxidase resulting in the production of H2O2 which reacts with a specific dye to form a pink colored product. The color intensity at 570nm or fluorescence intensity (530/585 nm) is directly proportional to the ascorbic acid concentration in the sample.

We would like to measure ascorbic acid in liver homogenates, which are in 0.25M Sucrose. We want to confirm the sucrose will interfere with the assay?

We have not tested the compatibility of sucrose with this assay. Based on the mechanism of the assay we see no reason why sucrose would interfere and believe the assay will work just fine.For more detailed product information and questions, please feel free to Contact Us.

BioAssay Systems的EnzyFluo™ERK磷酸化检测试剂盒的有丝分裂原活化蛋白激酶(MAPK / ERK)途径在细胞增殖,分化和迁移中起关键作用。有丝分裂原刺激最终导致ERK1(T202 / Y204)和ERK2(T185 / Y187)磷酸化。MAPK / ERK级联为癌症治疗的发展提出了许多有趣的药物靶标。BioAssay Systems基于细胞的ELISA可测量全细胞中双重磷酸化的ERK1 / 2,并将信号归一化至总蛋白质含量。这种简单有效的测定方法消除了细胞裂解液制备的需要,可用于研究激酶信号传导和激酶抑制剂对细胞的作用。在该测定中,细胞在96孔板中生长,并用配体或药物处理。然后将细胞固定并在孔中透化。使用荧光ELISA进行ERK1 / 2磷酸化(pERK),然后在每个孔中测量总蛋白。
