Cardiac Troponin I test kits

Cardiac Troponin I (cTnI) is protein found in cardiac muscle with a molecular weight of 22.5 kDa [4]. Troponin I is part of a three subunit complex comprising of Troponin T and Troponin C as well. Along with tropomyosin, this structural complex forms the main component that regulates the calcium sensitive ATPase activity of actomyosin in striated skeletal and cardiac muscle [5]. After cardiac injury occurs, Troponin is released into the blood 4-6 hours after the onset of pain. Troponin I remain elevated for 6-10 days, thus providing for a longer window of detection for cardiac injury as compared to other cardiac markers.

One Step Cardiac Troponin I (cTnI) Test is a simple test that utilizes a combination of anti-cTnI antibody coated particles and capture reagent to selectively detect cTnI in whole blood, serum or plasma or plasma. The minimum detection level is 1 ng/ml.
