Eco-friendly solutions are also available under ECO-TEK® offering the highest level of sustainability for manufacturing immunoassays without compromising on quality, sensitivity and accuracy.

Explore a wide range of immunoassay products, including:


Buffers and Stabilizers

We offer the specially crafted buffers tailored for both colorimetric and chemiluminescence-based assays, including popular techniques such as ELISA, Western Blotting, and IHC. Our range of stable and resilient blocking buffers, stabilizers, and diluents are conveniently ready-to-use, with many being ECO-TEK® certified.

Blocking and Stabilizing

Product portfolio includes traditional blocking buffers for ELISA and Blotting, as well as WellChampion® – Kementec’s new generation Plate Blocking & Protection Buffer for pre-coated plates.

Diluents and Stabilizers

Ready-to-use sample diluents and robust stabilizers demonstrate superior stabilization of proteins conjugated to Horseradish Peroxidase (HRP) and Alkaline Phosphatase (AP). These stabilizers prevent loss of enzyme activity and maintain the proteins molecular conformation.

Featured Products


We offer a broad portfolio of substrates including soluble Horseradish Peroxidase (HRP) substrates (TMB), soluble Alkaline Phosphatase (AP) substrates (pNPP) and precipitating substrates enabling different substrate formulations for immunoassays, featuring the following advantages:

  • Shelf life up to 4 years 
  • Outstanding sensitivity, stop-stability and shelf life stability
  • Negligible lot-to-lot variation
  • Ready-to-use
