Description	Direct determination of L-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, almond milk, yogurt, beer, champagne, apple juice, lemonade, grape juice, orange juice, cranberry juice, lime and lemon juice. My sample turns the strip very dark purple, how can I determine the L-lactate concentration? Very dark purple indicates that the diluted sample concentration is greater than 360 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 using your test strips with fruit juice and the color only develops on the corners of the strips. I know there are high levels of L-Lactate in the juice, so the strips should be very dark. What is wrong? The enzymes on the strips need to be around pH 7, and your fruit juice is likely pretty acidic. Adjust the pH of your samples with NaOH or another base until it is ca.7, and rerun the strips. You may also want to try diluting the sample in water, since high levels of lactate can "max out" the strips. This will also help with the pH since water is 7.

Overview	Application Direct determination of L-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 0-360 mg/L (undiluted) L-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 L-LACTIC ACID, or L-lactate, is generated by lactate dehydrogenase (LDH) under hypoxic or anaerobic conditions. L-lactic acid is added to many foods and beverages to give it a tart flavor. Increased levels of L-lactic acid in milk, egg, and fruit juices can be an indication of spoilage. In the wine industry, increasing levels of L-lactic acid and the decreasing levels of L-malic acid are monitored (Malolactic fermentation). In this process, the overall acidity of the wine is reduced and can lead to the improvement of the flavor of the wine. BioAssay Systems QuantiQuik L-Lactic Acid Test Strips are based on L-lactate dehydrogenase catalyzed oxidation of L-lactate in which the formed NADH reduces a chromogenic reagent. The intensity of product color is directly proportional to L-lactate concentration in the sample.
