For quantitative determination of ketone body (acetoacetate and 3-hydroxybutyrate) and evaluation of drug effects on its metabolism. Key Features: Sensitive and accurate. Uses 10 µ L sample. Linear detection range of 0.12 to 8 mM for each ketone body in 96-well plate assay. Convenient. The procedure involves adding a single working reagent, and reading the optical density at room temperature. High-throughput. Can be automated as a high-throughput 96-well plate assay for many samples per day. Method: OD340nm. Samples: Serum, plasma, urine etc. Species: All. Procedure: Assay takes 30 min. Kit size: 200 tests. Detection limit: 0.12 mM.
