More Details

  • CHOLINE and its metabolites play important roles in membrane structure integrity, cellular signaling and cholinergic neurotransmission. Aberrant regulation in choline metabolism has been associated with mental illness such as anxiety. BioAssay Systems method provides a simple, direct and high-throughput assay for measuring choline in biological samples. In this assay, free choline is oxidized by choline oxidase to βine and 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 choline concentration in the sample.

What are known interferences?

Chondroitin sulfate C (chondroitin-6-sulfate) appears to interfere with the assay; creating false positive results.For more detailed product information and questions, please feel free to Contact Us. Or for more general information regarding our assays, please refer to our General Questions.

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。
