D-Lactate Assay Kit – Information
Assay Genie’s Fluorometric D-lactate assay kit is based on lactate dehydrogenase catalyzed oxidation of lactate, in which the formed NADH reduces a probe into a highly fluorescent product. The fluorescence intensity of this product, measured at Ex/Em = 530/585 nm, is proportional to the lactate concentration in the sample.
For quantitative determination of D-lactate (D-lactic acid) and evaluation of drug effects on its metabolism.
D-Lactate Assay Kit – Key Features
- Sensitive and accurate. Detection limit of 1 μM and linearity up to 50 μM D-lactate in 96-well plate assay.
- Convenient. The procedure involves adding a single working reagent, and reading the fluorescence after 60 min. Room temperature assay.
- High-throughput. Can be readily automated as a high-throughput 96-well plate assay for thousands of samples per day.

Lactate is generated by lactate dehydrogenase (LDH) under hypoxic or anaerobic conditions. Monitoring lactate levels is, therefore, a good indicator of the balance between tissue oxygen demand and utilization and is useful when studying cellular and animal physiology. D-Lactate is produced in only minor quantities in animals and measuring for D-lactate in animal samples is a means to determine the presence of bacterial infection. Simple, direct and automation-ready procedures for measuring lactate concentration are very desirable.
