OxiSelect Ascorbic Acid Assay Kit (FRASC) |
|||
STA-860 | Cell Biolabs | 200 assays | EUR 672 |
Description: Ascorbic acid is a vital water-soluble antioxidant found in living organisms. Ascorbic acid is critical for a variety of functions related to tissue growth and wound healing, neurotransmitter formation, blood cholesterol levels, as well as free radical neutralization. The OxiSelect Ascorbic Acid Assay Kit is a quantitative assay for measuring ascorbic acid within various samples. The assay is based on the Ferric Reducing/Antioxidant Ascorbic Acid (FRASC) chemistry driven by the electron donating reducing power of antioxidants. The kit employs ascorbate oxidase, which allows the user to differentiate the ascorbic acid content from other antioxidants present within their sample. Ascorbic acid levels in a sample are determined by measuring the difference in optical density between two sample wells, one with and one without the enzyme. |

OxiSelect Total Glutathione (GSSG/GSH) Assay Kit |
|||
STA-312 | Cell Biolabs | 100 assays | EUR 622.8 |
Description: The OxiSelect Total Glutathione Assay Kit is a quantitative assay for measuring the total glutathione content within a sample (GSH/GSSG). Glutathione Reductase reduces oxidized glutathione (GSSG) to reduced glutathione (GSH) in the presence of NADPH. Subsequently, the chromogen reacts with the thiol group of GSH to produce a colored compound that absorbs at 405 nm. The total glutathione content in unknown samples is determined by comparison with the predetermined glutathione standard curve. The rate of chromophore production is proportional to the concentration of glutathione within the sample. The rate can be determined from the absorbance change over time. Metaphosphoric acid is provided to remove interfering proteins or enzymes from samples. |
OxiSelect Superoxide Dismutase Activity Assay, Trial Size |
|||
STA-340-T | Cell Biolabs | 20 assays | EUR 414 |
Description: Superoxide dismutase (SOD), which catalyzes the dismutation of the superoxide anion into hydrogen peroxide and molecular oxygen, is one of the most important antioxidant enzymes. SOD enzymes are classified into three groups: cytosolic CuZn-SOD, mitochondrial Mn-SOD, and extracellular Ec-SOD. Our OxiSelect Superoxide Dismutase Activity Assay uses a xanthine/xanthine oxidase (XOD) system to generate superoxide anions and a chromagen to produce a water-soluble formazan dye upon reduction by superoxide anions. The superoxide dismutase activity is determined as the inhibition or reduction of chromagen. |
OxiSelect Intracellular ROS Assay Kit (Green Fluorescence) |
|||
STA-342 | Cell Biolabs | 96 assays | EUR 762 |
Description: The OxiSelect ROS Assay Kit is a cell-based assay for measuring hydroxyl, peroxyl, and other reactive oxygen species activity within a cell.

OxiSelect Cellular Antioxidant Assay Kit (Green Fluorescence) |
|||
STA-349 | Cell Biolabs | 192 assays | EUR 644.4 |
Description: The OxiSelect Cellular Antioxidant Assay Kit is a cell-based assay for measuring the activity of an exogenous antioxidant compound within adherent cells. Cells are first cultured in a 96-well black fluorescence cell culture plate until confluent. Then the cells are pre-incubated with a cell-permeable DCFH-DA fluorescence probe dye and the bioflavonoid Quercetin, or the antioxidant sample being tested. After a brief incubation, the cells are washed, and the reaction started by adding the Free Radical Initiator. The Free Radical Initiator creates free radicals that convert the probe to highly fluorescent DCF. The Quercetin inhibits the formation of free radicals, and thus DCF formation, in a concentration dependent manner. |
