CheKine™ Total Antioxidant Capacity (TAC) Assay Kit

Product Information

  • Product name

    CheKine™ Total Antioxidant Capacity (TAC) Assay Kit

  • Application notes

    CheKine™ 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
    • FeSO4• 7H2O Standard
    • ascorbic acid (positive control)

  • Features & Benefits

    • Determination of Total Antioxidant Capacity in serum, plasma, cell/tissue samples, urine and bacteria samples.
    • Detect biological samples at a level of 0.15-3 mM.
    • 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
