TMB Products and Substrates

3,3',5,5'-TETRAMETHYLBENZSIDINE (TMB) is a substrate for horseradish peroxidase (HRP). Biopanda offers a wide range of TMB-based products, ranging from ready-to-use liquid solutions to the base TMB powder, as well as acid-based stop solutions and diluents. General features of our TMB products are as follows:

  • Stable - shelf life ranging from 12-36 months.
  • Safe - no harmful organic solvents, eg. DMSO or DMF.
  • Consistent - lot to lot consistency.
  • Reliable - low background, no colour changes.
  • Performance - superior sensitivity and linearity.

Product Name Product No. Description
3,3',5,5'-Tetramethylbenzine (base) TMB-BS ≥98% purity. Stable for at least 5 years when stored at + 2-8 °C.
3,3',5,5'-Tetramethylbenzine dihydrochloride TMB-HC ≥98% purity. Stable for at least 5 years when stored at + 2-8 °C.
TMB solution I (2 in 1) TMB-S-001 One component format - ready to use. Recommended for Quantitative ELISA.
TMB solution II (2 in 1) TMB-S-002 One component format - ready to use. Like TMB solution I, solution II is also designed for ELISA procedure but has a higher activity level.
TMB solution III (2 in 1) TMB-P-001 One component format - ready to use. Designed for membrane immuoblotting applications. This develops a purple end product.
TMB solution IV (1 + 1) TMB-S-003 Two component format - mix just before use. Like solutions I and II, is also designed for ELISA procedure.
TMB solution V (1 + 1) TMB-P-002 Two component format - mix just before use. Designed for membrane immuoblotting applications. This develops a purple end product.
TMB solution VI (1 in 1) TMB-WHP Specifically designed for the determination of chlorine and hydrogen peroxide (H2O2).
TMB solution VII (2 in 1) TMB-S-004 One component format also designed for ELISA but more sensitive than TMB solutions I and II.
TMB solution VIII (2 in 1) TMB-P-003 One component format - ready to use. Designed for the membrane immuoblotting procedure. This develops a blue end product.
TMB solution IX (1 + 1) TMB-P-004 Two component format - mix before use. Designed for immuoblotting procedure. This develops a blue end product.
TMB solution X (2 in 1) TMB-S-005 This one component solution is the most sensitive substrate for ELISA, surpassing that of TMB solution VII. Short incubation time allowing for fast assay development.
TMB diluent TMB-D-001 Designed for diluting TMB solutions I and II.
TMB stop solution I STP-001 Supplied in liquid format. For general use to stop colour development in ELISA.
TMB stop solution II STP-002 Supplied in liquid format. This solution can prevent the formation of precipitate of TMB end product in ELISA.
TMB stop solution III STP-003 This stopping solution is capable of retaining the OD reading for over 2 hours after stopping.
