Troponin T ELISA Kit (TnT)


Human troponin T ELISA kit can be used for measuring in vitro quantitative levels of  TnT (troponin T) in human cell culture supernatant, plasma, serum, other biological fluids and cell lysates. This assay has a minimum sensitivity limit of 5.9 pg/ml.


Troponin T (TnT) is a group of homologous proteins which have a molecular mass between 31-36 kDa and are useful in the laboratory to diagnose heart attack since they are released into the bloodstream when the heart muscles become damaged. It binds the troponin complex to tropomyosin, troponin I which can inhibits actomyosin ATPase and troponin C which mediates calcium dependency through its 4 binding sites for calcium. It functions in binding to tropomyosin which thereby helps to position it on actin and the rest of the troponin complex is responsible for modulating the contraction of striated muscle. Elevated levels have also been identified in patients having unstable angina.

Some of the uses for this protein include monitoring acute coronary syndromes and prognosis estimation, the exclusion diagnosis of acute myocardial infarction and the possible use in monitoring patients with nonischemic causes of cardiac injury.


All reagents supplied need to be stored at 2 °C – 8 °C, unopened reagents will retain reactivity until expiration date. Do not use reagents beyond this date.

  • Microwell Plate: Antibody specific to TnT is pre-coated onto a 96-well plate.
  • Standards: Concentration ranging between 15.6 – 1,000 pg/ml.

The minimum detection sensitivity level of human TnT (troponin T) using current troponin T ELISA kit was 5.9 pg/ml. The dynamic range for this assay is 15.6 – 1,000.0 pg/ml.

I am a first time user and found that your instruction manual was very easy to follow. The insulin ELISA assay performed well and I was happy with the results that were generated.

J. Thomas
Senior Technician / Addenbrooke’s Hospital

I carried out a pilot study comparing the performance of many ELISA assay's from different suppliers and found your kits to be one of the better performers. We observed good linearity and tight replicates.
