More Details:
LACTIC ACID, or lactate, is generated by lactate dehydrogenase (LDH) under hypoxic or anaerobic conditions. 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.
Furthermore, since D-lactate is a specific indicator of bacteria fermentation, its measurement can be used to determine the freshness of milk, meat and fruit juices. Elevated levels of D-lactate in wine is an indication of lactic acid bacteria contamination.
Gentaur Genprice QuantiQuik™ D-Lactate Test Strips are 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 D-lactate concentration in the sample.
