Catalase Assay Kit
Catalase Assay Kit provides a simple and easy colorimetric method for measuring the catalase activity in a variety of biological samples such as whole blood, red blood cells, serum, tissue and cell lysates. In this assay, catalase in samples decomposes hydrogen peroxide into water and oxygen, and the residual hydrogen peroxide oxidizes the chromogenic substrate under the catalysis of peroxidase into a red-colored product (N-(4-antipyryl)-3-chloro-5-sulfonate-p-benzoquinonemonoimine) which has a maximum absorption at 520nm. With a standard curve derived from hydrogen peroxide standard, the catalase activity in samples can be determined. Package: 100T

DAF-FM DA (NO fluorescence probe)
DAF-FM DA (3-Amino,4-aminomethyl-2',7'-difluorescein, diacetate) is the latest generation of fluorescent probes for quantitative detection of nitric oxide (NO). It has many improvements over the previously commonly used nitric oxide fluorescence detection probe DAF-2 diacetate. First, the fluorescent products formed from the DAF-FM DA reaction are less affected by pH and not affected in pH higher than 5.5. Secondly, the fluorescent products are more stable and not easy to quench, facilitating. Moreover, the DAF-FM DA is more sensitive in NO detection and the lowest working concentration can be down to 3nM. Package: 100T

Hydrogen Peroxide Assay Kit
Hydrogen Peroxide Assay Kit provides a simple and rapid assay for quantitative determination of hydrogen peroxide (H 2 O 2 ) in a variety of biological samples such as cultured cells or tissues, cell lysates, serum, urine, and plasma. This assay utilizes the chromogenic Fe 3+ -xylenol orange reaction, in which a purple complex (λmax = 560 nm) is formed when Fe 2+ is oxidized to Fe3+ by H 2 O 2 present in the sample. The amount of purple-colored product is proportional to the H 2 O 2 level in the sample. Package: 150T

Lipid Peroxidation MDA Assay Kit
Malondialdehyde (MDA) is a natural product of lipid oxidation in organisms. Lipid oxidation occurs when animal or plant cells are exposed to oxidative stress. Some oxidative fatty acids gradually degrade into a series of compounds, such as MDA, during which the level of lipid oxidation can be measured by detecting the MDA level.Therefore, MDA is widely used as an indicator of lipid oxidation. Package: 500T
