For quantitatve determination of acetaldehyde and evaluations of drug effects on its metabolism. Key Features: Fast and sensitive. Linear detection range (50µ L sample) : 0.5 µ M to 60 µ M acetaldehyde in 96-well plate assay. High-throughput. The procedure involves adding a single working reagent, and reading the absorbance after 30 minutes. Room temperature assay. No 37° C heater is needed. Convenient. Homogeneous "mix-incubate-measure" type assay. Can be readily automated on HTS liquid handling systems for processing thousands of samples per day. Method: FL530/585nm. Samples: Biological samples (e.g. plasma, serum, urine, tissue and culture media) and food/beverage samples (e.g. wine, coffee, and juice) . Species: All. Procedure: Assay takes 30 min. Kit size: 100 tests. Detection limit: 0.5 µ M.
