D-Lactic Acid Quick Test Strips

产品说明

一般描述

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.

特点和优势

• 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.

适用性

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

原理

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.
