Description	Direct determination of D-Lactate concentrations in food and beverage samples as well as biological (e.g. urine, blood, etc.) samples.
Faqs	What samples have you tested? The strips have been tested on red wine, white wine, homogenized whole milk, cultured buttermilk, yogurt, malt mash, beer and lemonade. My sample turns the strip very dark purple, how can I determine the D-lactate concentration? Very dark purple indicates that the diluted sample concentration is greater than 180 mg/L. To obtain a more accurate concentration, the sample should be further diluted and retested. For example, if the sample was diluted 5x, try diluting 21x. I don’t have access to a pipetteman. How can I accurately measure out my samples? We offer exact volume transfer pipettes as an accessory. For samples requiring a 21x dilution, order the 20 uL transfer pipettes (TP20). For samples requiring a 5x dilution, order the 100 uL transfer pipettes (TP100). Can I store unused reagents for future use? Yes, unused reagents can be stored according to the assay protocol. The strips should be kept in a dry, cool location and protected from light. I am running sour beer samples and know that there should be high levels of lactate in the samples. However, the strips are very patchy and only have color in the corners. What is wrong? The enzymes in the strips need to be around pH 7 to work properly. Your sour beer may be too acidic, so please adjust the pH with NaOH or another base until it is pH ca.7 and rerun the strips. If the levels are quite high, you may also want to dilute the sample in water which will make the sample closer to pH 7 as well since high levels of lactate "max out" the strip.

Overview	Application Direct determination of D-lactic acid concentrations in food and beverage samples as well as biological samples. Note: Requires access to pipettes for dilution. We offer pipettes that can be purchased separately: 20 uL Pipettes (Catalog: TP-20), 100 uL Pipettes (Catalog: TP-100), or 400 uL Pipettes. (Catalog: TP-400) Key Features Fast and sensitive. Use of 20 or 100 uL sample. Semi-quantitative measurement between 0-180 mg/L (undiluted) D-lactic acid. Convenient. No expensive lab equipment needed. Sample treatment and assay can be performed in under 15 minutes. Method Visual Samples Wine, beer, milk, etc Species All Size 10 tests Shelf Life 6 months 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. BioAssay Systems 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.
