Phenylalanine Assay Kit, BioAssay™

L-Phenylalanine is one of the twenty common amino acids and an important precursor for several key signal molecules such as dopamine, norepinephrine, epinephrine, and the skin pigment melanin. It is found naturally in the breast milk of mammals, and used as nutritional supplements in food and drink products. The genetic disorder phenylketonuria is the inability to metabolize phenylalanine. Individuals with this disorder are known as "phenylketonurics". Individuals who cannot metabolize phenylalanine must monitor their intake of protein to control the buildup of phenylalanine.||L-Phenylalanine Assay Kit provides a convenient fluorometric means to measure L-phenylalanine in biological samples. In the assay, L-phenylalanine is oxidized by phenylalanine dehydrogenase, producing NADH, which reduces a fluorescent dye to a highly fluorescent product. The resulting fluorescence intensity (lexc/em=530/595nm) is linear to the L-phenylalanine concentration in the sample.||Key Features:|Safe: Non-radioactive assay.|Sensitive and accurate: Linear detection range of 2-300uM L-phenylalanine.|Convenient and high-throughput: Homogeneous "mix-incubate-measure" type assay. No wash and reagent transfer steps are involved. Can be readily automated on HTS liquid handling systems for processing thousands of samples per day.||Applications:|Determination of L-phenylalanine in serum, urine and other biological samples.||Kit Components:|P4060-05G1: Assay Buffer, 1x10ml |*P4060-05G2: Enzyme A, 1x1vial|P4060-05G3: Enzyme B, 1x120ul|P4060-05G4: Standard, 1x120ul|P4060-05G5: NAD Solution, 1x1ml |P4060-05G6: Probe, 1x750ul ||Storage and Stability:|Store all components at -20°C.
