Features and Benefits

Fast and sensitive. Use of 20 or 100 µL sample. Semi-quantitative measurement between 0-180 mg/L (undiluted) D-lactic acid. Sample treatment and assay can be performed in under 15 minutes.

General description

Lactic acid, or lactate, is generated by lactic acid 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 bacteria fermentation, its measurement can be used to determine the freshness of milk, meat and fruit juices. Elevated levels of D-lactic acid in wine is an indication of lactic acid bacteria contamination.

Principle

The D-Lactic Acid Quick Test Strips are based on D-lactic acid dehydrogenase catalyzed oxidation of D-lactic acid in which the formed NADH reduces a chromogenic reagent. The intensity of product color is directly proportional to D-lactic acid concentration in the sample.

Suitability

This kit is suitable for the detection of D-lactic acid in a variety of food and beverage samples.
