Troponin T (Tn-T) ELISA Kit

  • Created on the 16 May, 2017.

BACKGROUND

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. Troponin is a myofibrillar protein that is found in striated musculature, it is a 3 protein complex that is made up of troponin C, troponin T and troponin I. It is troponin T which 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. Troponin T 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. In patients with stable coronary artery disease, the concentrations of troponin T have been significantly associated with incidence of heart failure and cardiovascular death. Elevated levels have also been identified in patients having unstable angina.

In the cytosol, TnT exists either in a protein-bound or free unbound form. The protein bound troponin T is usually released during the later stages of irreversible myocardial damage, whereas, the free (unbound) form is released in the early stages of myocardial damage. 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.

INTENDED USE

Human troponin T ELISA kit can be used for measuring in vitro quantitative levels of human TnT in cell culture supernatant, plasma, serum, other biological fluids and cell lysates. This assay has a minimum sensitivity limit of 2.54 ng/L.

SENSITIVITY

The minimum detection sensitivity level of human TnT using this human troponin T ELISA kit was 0.27 ng/L. The dynamic assay range for this kit is 5.0 – 1,000.0 ng/L.

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