    • Intended Use
      BUF067A is a high performance TMB (3,3´, 5, 5´- tetramethylbenzidine) solution, recommended for use in ELISA as a substrate for horseradish peroxidase (HRP).

      BUF067A contains TMB, substrate buffer and hydrogen peroxide in a safe, ready to use solution. The activity of TMB has been optimised to enable increased sensitivity, minimal background and rapid development.

      BUF067A produces a deep blue colour during the enzymatic degradation of H2O2 by horseradish Peroxidase. The reaction may be stopped with 0.25M sulphuric acid, resulting in a yellow colour read at 450nm.

      TMB SENSITIVE PRESTAINED is more sensitive than other TMB reagents offered by Bio-Rad.

      TMB SENSITIVE PRESTAINED is stained with a red indicator to eliminate pipetting errors. The red indicator does not interfere with the sensitivity or the stability of the substrate. It does not absorb light at the wavelengths used for the substrate and will disappear after addition of the stop solution.

    • Instructions For Use
      1. It is recommended that 100ul of BUF067A TMB substrate is used per microtiter well. Pour the desired amount of substrate into a sealed container and allow it to reach room termperature in the dark.

      2. Add 100ul of substrate solution per microtiter well.

      3. Allow development of the substrate solution. Development time is typically 5-15 minutes. For best results, the plate should be kept in the dark during incubation e.g. wrapped in tinfoil.

      4. For kinetic assays, read absorbance at 655nm (blue). For endpoint assays, add an equal volume of 0.25M sulphuric acid and read the absorbance at 450nm (yellow). This endpoint solution is stable for up to one hour.

      N.B. If reduced intensity is required, it is recommended that the development time is reduced or the antibody/conjugate is diluted further. (Dilution of BUF067A is not recommended).
