BQC Redox Technologies products

The unique portable device is able to measure in less than a minute with a single drop of your sample. Traditional methods are more laborious and time-consuming than with BQC devices. Furthermore, it is possible to know the total TAC measurement and maintain the native conditions of the sample.

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 collagen biosynthesis, carnitine and catecholamine metabolism, and dietary iron absorption.

Among reactive aldehydes, malondialdehyde (MDA) has been extensively used as an index of LPO. Malondialdehyde (MDA) can be generated by oxidizing agents that alter lipid structure, creating lipid peroxides.

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 diseases.

BQC Thiol Quantification Assay Kit is a selective, easy, and quick assay for measuring free thiols and disulfides groups in biological samples.

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-), are used for the indirect determination of NO.

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 species.

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 system.

APX is a central component of the ascorbate-glutathione (AsA-GSH) cycle that is one of the most important components of plant antioxidant defense.
