Lactate Assay Kit: Sensitive and accurate. Detection limit of 0.05 mM and linearity up to 2 mM L-Lactate in 96-well plate assay. For cell culture samples containing phenol red: detection limit of 0.1 mM and linearity up to 1 mM L-Lactate in 96-well plate assay.Convenient. The procedure involves adding a single working reagent, and reading the optical density at time zero and at 20 min. Room temperature assay. No 37 degree C heater is needed.High-throughput. Can be readily automated as a high-throughput 96- well plate assay for thousands of samples per day.
