More Details

  • CITRATE is an intermediate in the citric acid cycle and is involved in fatty acid synthesis. BioAssay Systems’ Citrate Assay Kit provides a simple, and automation-ready procedure for measuring citrate concentration. Citrate is converted into pyruvate which is then oxidized with the conversion of the dye into a colored and fluorescent form. The color intensity at 570 nm or fluorescence intensity at λex/em = 530/585 nm is directly proportional to the citrate concentration in the sampl
