Diverse and comprehensive range of antioxidant kits

Find the one to meet your expectations!

Free radicals and reactive oxygen species (ROS) are highly reactive molecules that are generated by normal cellular processes, environmental stress, and UV irradiation. ROS react with cellular components, damaging DNA, carbohydrates, proteins, and lipids causing cellular and tissue injury. Organisms have developed complex antioxidant systems to protect themselves from oxidative stress, however, excess ROS can overwhelm the systems and cause severe damage.

Excess production of reactive oxygen species can also lead to inflammation, premature aging disorders and several disease states including cancer, diabetes, and atherosclerosis that are possibly part of your research areas ...

5 new antioxidant kits have just been released for testing the antioxidative capacity of biological fluids,
cells, tissues and other samples (natural products, food additives, cosmetics, small molecules)
to neutralize a variety of free radicals.

The ZenBio FRAP assay measures the reduction capacity of an antioxidant to reduce Fe(III) to Fe(II) in a low pH environment. This reduction reaction allows a stable ferrous-tripyridyltriazine complex to form as a colored product with strong absorbande at 593nm. Fe(II)SO4 is used as a positive control.

The ZenBio Activated ABTS assay measures the capacity of an antioxidant to reduce pre-formed ABTS radical cation. This assay differs from the AOX-1 kit by pre-forming the ABTS radical cation prior to testing antioxidant activity eliminating any potential additional effects on other radicals. Trolox serves as the positive control reduces the ABTS radical cation in a dose dependent manner. 

The ZenBio Ferrous Iron Chelating (FIC) assay measures the ability of a test sample to chelate Fe(II). Increased sample chelation is measured by a decrease in absorbance of the Fe(II)-Ferrozine complex. EDTA serves as the positive control. 

The ZenBio Cupric Ion Chelating (CIC) assay measures the ability of a test sample to chelate Cu(II). Increased sample chelation is measured by a decrease in absorbande of the Cu(II)-Pyrocatechol Violet complex. EDTA serves as the positive control.

The ZenBio Total Phenolic ontent assay measures the phenolic content of a test sample using the Folin-Ciocalteu reagent. Gallic Acid serves as the comparator control for the assay. 

Zenbio kits are based on 14 antioxidant mechanisms.
Whether you need to work in a low pH environment, or you want to test the anti-oxidant capacity of a
biological or non-biological sample, you'll find the most suitable one for your research.
