QuantiQuik L-Lactic Acid Quick Test Strips (10 Strips)

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 acidity of the wine is reduced and can lead to the improvement of the flavor. 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. Materials required but not provided: pipetting devices FREQUENTLY ASKED QUESTIONS: Q: My doctor said that I need to get my lactate levels tested. Can I use this product with my urine/blood? A: These strips are not for clinical use, and are for RESEARCH USE ONLY. This means that they should never be used for health-related decisions. Q: I didn't receive a protocol sheet with this kit. Where should I go to get instructions? A: The protocol sheet is included in the kit. You can also contact us for a pdf. Q: How should I store these strips? A: The strips can be stored at room temperature and kept away from heat/moisture. They have a 6 month shelf life, and should be used within a week of opening. Q: My sample turns very dark blue, how can I determine the lactate concentration? A: The lactate is too high for the strip to detect. Dilute your sample in water and re-run the test with another strip.
