More Details

• D-Lactate, or D-lactic acid, is generated by D-lactate dehydrogenase (LDH) under hypoxic or anaerobic conditions. D-lactic acid is produced in only minor quantities in animals and measuring for D-lactic acid in animal samples is a means to determine the presence of bacterial infection. Furthermore, since D-lactic acid is a specific indicator of bacterial fermentation, its measurement can be used to determine the freshness of milk, meat and fruit juices. Elevated levels of D-lactic acid in wine are an indication of lactic acid bacteria contamination.BioAssay Systems' PractiChrom™ D-lactate Assay Kit is based on D-lactate dehydrogenase catalyzed oxidation of D-lactate in which the formed NADH reduces a chromogenic reagent. The intensity of product color is directly proportional to the D-lactate concentration in the sample.
