Product Description

Ascorbic acid (the L-enantiomer commonly known as vitamin C) is an important antioxidant found in living organisms and applied as additives in food and other industrial processes. By reacting with reactive oxygen species, it protects the cell from oxidative damages. This Ascorbic Acid Assay Kit provides a simple, direct and high-throughput assay for measuring ascorbic acid. In this assay, ascorbic acid is oxidized by ascorbate oxidase resulting in the production of H2O2 which reacts with a specific dye to form a pink colored product. The color intensity at 570nm or fluorescence intensity (530/585 nm) is directly proportional to the ascorbic acid concentration in the sample. This kit is suitable for the determination of ascorbic acid in biological samples such as serum, plasma, urine, saliva, milk, and tissue/cell lysates. Sample size: 20ul Linear Detection Range: Colorimetric Assay: 6 to 1000uM ascorbic acid Fluorometric Assay: 1 to 100uM ascorbic acid Applications: Assays: Ascorbic acid in biological samples such as serum, plasma, urine, saliva, milk, and tissue/cell lysates Drug Discovery/Pharmacology: Effects of drugs on ascorbic acid metabolism Kit Components: A3774-61A: Enzyme Mix, 1x120ul A3774-61B: Standard, 1x400ul. 10mM Ascorbic acid A3774-61C: Assay Buffer, 1x10ml A3774-61D: Dye Reagent, 1x120ul Materials Required But Not Provided: Optical density plate reader Fluorescence plate reader.
