An Aptamer-based Biosensor for Troponin I Detection in Diagnosis of Myocardial Infarction
Background: Acute myocardial infarction (MI) accounts for one third of deaths. Cardiac troponin I (TnI) is a reliable biomarker of cardiac muscle tissue injury and is employed in the early diagnosis of MI.Objectives: In this study, a molecular method is introduced to early diagnosis of MI by rapid detection of TnI.Materials and Methods: The detection method was based on electrochemical aptasens...
متن کاملThe solution structure of a cardiac troponin C-troponin I-troponin T complex shows a somewhat compact troponin C interacting with an extended troponin I-troponin T component.
We have investigated the structure of the cTnC-cTnI-cTnT(198-298) calcium-saturated, ternary cardiac troponin complex by small-angle scattering with contrast variation. Shape restoration was also applied to the scattering information resulting from the deuterated cTnC subunit, the unlabeled cTnI-cTnT(198-298) subunits, and the entire complex. The experimental results and modeling indicate that ...
متن کاملCardiac Troponin I as Compared to Troponin T for the Detection of Myocardial Damage in Horses
BACKGROUND Different cardiac troponin I (cTnI) assays give different results. Only 1 manufacturer has marketed troponin T (cTnT) assays. Therefore, cTnT often is preferred for detection of myocardial infarction in human patients. Studies of cTnT in horses are limited. OBJECTIVES To compare a cTnI and a high-sensitive cTnT assay (hs-cTnT) in horses. ANIMALS Cardiac troponin I and cTnT were d...
متن کاملHydrodynamic properties of bovine cardiac troponin-I and troponin-T.
Bovine cardiac troponin-I (TN-I) and troponin-T (TN-T) have been examined in solution using ultracentrifugation, gel filtration, and viscosity. A new method of purifying TN-T, employing hydroxylapatite chromatography in 6 M urea, is reported. Cardiac TN-T (Mr = 36,000) undergoes a reversible, concentration-dependent association in nondenaturing buffers, probably to a tetramer. The Stokes radius...
متن کاملDephosphorylation specificities of protein phosphatase for cardiac troponin I, troponin T, and sites within troponin T
Protein dephosphorylation by protein phosphatase 1 (PP1), acting in concert with protein kinase C (PKC) and protein kinase A (PKA), is a pivotal regulatory mechanism of protein phosphorylation. Isolated rat cardiac myofibrils phosphorylated by PKC/PKA and dephosphorylated by PP1 were used in determining dephosphorylation specificities, Ca(2+)-stimulated Mg(2+)ATPase activities, and Ca(2+) sensi...
