BQC ABTS Assay Kit involves the direct production of the blue/green ABTS•+ chromophore, which has absorption maxima at 734 nm. After that, antioxidant compounds present in the sample reduce ABTS and produce a decoloration of the solution which is proportional to the antioxidant activity and the concentration of the ...

Vitamin C or Ascorbic Acid is a water-soluble vitamin essential for plants and animals. Humans, unlike other animals, are unable to synthesize vitamin C on their own so it must be obtained from the diet. Vitamin C is a strong antioxidant that provides protection against oxidative stress-induced cellular damage by scavenging of reactive oxygen species. Vitamin C is also an essential co-factor for ...

BQC Nitrite Assay Kit is a fast and simple method for the determination of nitrite in a wide variety of samples. Nitric oxide (NO) is an important signalling molecule that participates in virtually every cellular and organ function in the body. NO is a gaseous free radical with a short half-life in vivo. Therefore, the levels of the more stable NO metabolites, nitrite (NO2-) and nitrate (NO3-), ...

Superoxide dismutases (SOD) are metalloenzymes that catalyze the conversion (dismutation) of the superoxide anion (O2•−) into molecular oxygen (O2) and hydrogen peroxide (H2O2), playing a key role in the cellular antioxidant defense ...

BQC ORAC Assay Kit is based on the inhibition of fluorescein oxidation by peroxyl radical in the presence of antioxidants. Peroxyl radical (ROO·) is produced by a free radical initiator (AAPH: 2,2’-azobis-2- methylpropanimidamide dihydrochloride) which produces a fluorescent quenching of fluorescein over time. The presence of antioxidants inhibits the free radical damage to ...

Reactive oxygen (ROS) and nitrogen (RNS) species are produced in metabolic and physiological processes and can be overproduced in response to different stimuli. Organisms have different enzymatic and non-enzymatic antioxidative mechanisms to ameliorate the harmful effects of these oxidant ...

BQC DMPD Antioxidant Capacity Assay Kit is an easy and quick assay to measure TAC in beverages, food samples and plant extracts. This TAC Assay Kit is based on the N,N-dimethyl-ρ-phenylenediamine (DMPD) method. In this method, the DMPD radical (DMPD•+) which is a purple colored (λmax = 533 nm) stable cation radical, is reduced by hydrogen-donating antioxidants to the colorless ...

Catalase Activity Assay Kit consists of a reaction giving rise to a compound that forms a complex with the chromogen. This reaction produces a purple color directly proportional to catalase activity that can be determined by means of a simple and fast spectrophotometrical measure. This enzyme catalyzes the reaction that consumes hydrogen peroxide, transforming it into water and oxygen. Since it ...

Lipid peroxidation (LPO) is a well-known example of oxidative damage in cell membranes, lipoproteins, and other lipid-containing molecules in conditions with oxidative stress. Lipid peroxidation may contribute to the pathology of many diseases including cardiovascular diseases, cancer, and neurodegenerative ...
