Description
Specification
| Product name | Micro Total Antioxidant Capacity (TAC) Assay Kit |
| Applications notes | 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. |
Product Properties
| Kit components | • Assay Buffer (10X) • Substrate Diluent • Substrate • Reaction Buffer • ascorbic acid (positive control) |
| Features & Benefits | • 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. |
| Usage notes | • 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. |
| Storage instructions | 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. |
| Shipping | Gel pack with blue ice. |

Additional Information
| Background | 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.) |
