CheKine™ Micro Total Antioxidant Capacity (TAC) Assay Kit

Antioxidants play an important role in preventing the formation and scavenging of free radicals and other potentially toxic oxidizing species. There are three categories of antioxidant species: enzyme systems (GSH reductase, catalase, peroxidase, etc.), small molecules (ascorbate, uric acid, GSH, vitamin E, etc.) and proteins (albumin, transferrin, etc.)

• Determination of Total Antioxidant Capacity in serum, plasma, cell/tissue samples, urine and bacteria samples. • Using a stronger antioxidant, sascorbic acid as positive control, instead of the frequently-used Trolox. • The reaction is carried out under acidic conditions, which can inhibit some endogenous interference factors.

Storage at -20°C and Keep from light immediately upon receipt. Kit has a storage time of 12 months from receipt. Refer to list of materials supplied for storage conditions of individual components.

CheKine™ Micro Total Antioxidant Capacity (TAC) Assay Kit provides a simple and easy colorimetric assay for measuring Total Antioxidant Capacity in serum, plasma, cell culture supernatants, urine, tissue/ cell lysates and other biological fluids. In this assay, Fe3+-TPTZ is reduced by antioxidant to Fe2+-TPTZ. The enzyme catalyzed reaction products Fe2+-TPTZ can be measured at a colorimetric readout at 593 nm.

• It is recommended to perform several dilutions of your sample to ensure the readings are within the standard value range. • Fresh samples are necessary for good results. If not assayed immediately, samples can be stored at -80°C for one month. • Can not use EDTA as the anticoagulant for serum and plasma samples. The samples also can not contain DTT, Mercaptoethanol, Tween, Triton, NP-40.
