Our products

Product category: Substrates

OPD Tablets for colorimetric detection of Horseradish Peroxidase activity in ELISAs.

OPD Tablets for colorimetric detection of Horseradish Peroxidase activity in ELISAs.

Ortho-Phenylenediamine (OPD) is a water soluble chromogenic substrate that produces a yellow color during the enzymatic degradation of hydrogen peroxide by horseradish peroxidase (HRP) with an absorption maximum at 450 nm. After addition of sulfuric acid a very stable orange end solution is obtained that can be read at 490 nm.

Kem-En-Tec Diagnostics offers:

  • Fizzing OPD tablets: 2 mg tablets are available as fizzing, buffer-containing tablets (#4110-100)

Product category: Substrates


FAST RED is a sensitive chromogenic substrate for use in immuno-histochemistry and immunoblotting procedures.

FAST RED offers an Alkaline Phosphatase immunostaining system which produces a red stain precipitate at the site of the antigens.

Each tablet contains:

  • 2 mg FAST RED chromogen
  • 0.5 mg naphthol phosphate
  • 0.4 mg levamisole (an inhibitor of endogenous enzyme activity).
1 tablet is dissolved in 2 ml of 0.1M TRIS Buffer.

Standard package size is 50 tablets/vial.

  • Stable and robust
  • Negligible batch-to-batch variation
  • Development time: 5-30 minutes
  • 18 -24 months at 2-8° C
  • For long term storage Fast Red tablets should be kept at -20°C

Ready-to-use TMB Substrates

Kem-En-Tec Diagnostics offers a series of Liquid TMB Substrates for ELISA


Kem-En-Tec Diagnostics offers a series of Liquid TMB Substrates (3,3´, 5, 5´- tetramethyl-benzidine) for ELISA with a stability lifetime of up to 4 years. Our TMB solutions provide ready-to-use, chromogenic substrates that yield a blue color whose absorbance is read at 620-655 nm. The reaction can be stopped with a low concentration of sulfuric acid resulting in a yellow color with an absorbance read at 450 nm and a 2-3 fold increase in sensitivity compared to the non-stopped absorbance reading. The stop-solutions recommended for each product guarantee an extended stop stability of the measured absorbance, with an OD decreases after 1 hour lower than 8%.

  • Free of harmful organic solvents
  • Aqueous based
  • Ready-to-use
  • Negligible batch-to-batch variations
  • Recommended stop solutions do not have hazardous acid concentrations
  • Environmental sustainable – ECO-TEK labelled
  • A shelf life up to 4 years
TMB EASE a low concentrated TMB products for the direct transfer from 2 mg OPD tablets to the TMB platform

TMB ONE an extremely stable and robust TMB substrate

TMB PLUS2 a cost effective improved version of Kem-En-Tec Diagnostics TMB PLUS

TMB X-tra 60% higher OD values compared to the sensitivity of TMB ONE

TMB X-tnd same sensitivity as the TMB X-tra supporting a wide dynamic range. Allows OD-readings of up to 5,8 mAbs with NO precipitation within 60 min after stop of reaction

TMB SENS for high superior sensitivity and fastest assay development

Ready-to-use pNPP Substrates

Kem-En-Tec Diagnostics pNPP substrates are liquid buffer solutions

Kem-En-Tec Diagnostics pNPP (p-NitroPhenyl Phosphate) substrates are liquid buffer solutions containing stabilized pNPP used for measuring Alkaline Phosphatase activity. Current methods for making pNPP-solutions involve dissolving the pNPP powder in proper buffers or diluting pNPP concentrates. The stability of these solutions is normally one day. By contrast, our ready-to-use mono-component substrates are stable up to 36 months from manufacture date when stored at 2-8°C, without loss of activity (for details see below).

  • Free of harmful organic solvents 
  • Aqueous based
  • Ready-to-use liquid
  • Highly active and stable formulations
  • Negligible batch-to-batch variations
pNPP Kem-En-Tec Diagnostics most sensitive pNPP substrate

pNPP ONE Kem-En-Tec Diagnostics most robust pNPP substrate,- recommended in hot climate countries

Blotting Buffers for ELISA and Membrane

Synthetic Blocking Buffer – ELISA
Synthetic Blocking Buffer for ELISA – blocks all potential binding sites of nonspecific interaction and for reducing background signal.
After the coating step, the Synthetic Blocking Buffer for ELISA is added
to the washed microwells and the plate is incubated for 5-10 min. at RT.
The solution is then removed from the wells by aspiration or inversion.

  • Improves assay sensitivity and the Signal-To- Noise ratio in ELISAs
  • Compatible with a wide variety of antibodies
  • Highly effective and stable
  • High blocking capacity
  • Improves signal-to-noise ratio
  • Reduces the risk of false positive cross reactions
