hs-cTn ELISA Kit (Cardiac Troponin)

INTENDED USE

Human hs-cTn ELISA kit is intended for measuring in vitro quantitative concentrations of high sensitive cardiac troponin (hs-cTn) in human plasma, cell lysates, serum, other biological fluids and cell culture supernatant. This assay has a minimum sensitivity limit of < 11.3 pg/ml.

BACKGROUND

Cardiac troponins (cTn) have now become the markers of choice for patients with acute coronary syndrome (ACS). The troponins are regulatory proteins which are present in cardiac and skeletal muscles. The skeletal and cardiac subforms for TnI and troponin TnT are distinct and this has led to the development of many immunoassays in order to differentiate between them.

Rapid advances in immunoassay technologies has allowed manufacturers to develop and produce troponin assays with unprecedented precision and high analytic sensitivity. These assays can now detect plasma levels as low as 11.3 pg/mL and over a range that is between 0 –2,000 pg/mL. It is now even possible to measure low levels in the plasma samples of healthy individuals.
