Use a concentration of 1 µg/ml. Detects a band of approximately 40 kDa (predicted molecular weight: 36 kDa).
Troponin T is the tropomyosin-binding subunit of troponin, the thin filament regulatory complex which confers calcium-sensitivity to striated muscle actomyosin ATPase activity.
Heart. The fetal heart shows a greater expression in the atrium than in the ventricle, while the adult heart shows a greater expression in the ventricle than in the atrium. Isoform 6 predominates in normal adult heart. Isoforms 1, 7 and 8 are expressed in fetal heart. Isoform 7 is also expressed in failing adult heart.
Involvement in disease
Defects in TNNT2 are the cause of cardiomyopathy familial hypertrophic type 2 (CMH2) [MIM:115195]. Familial hypertrophic cardiomyopathy is a hereditary heart disorder characterized by ventricular hypertrophy, which is usually asymmetric and often involves the interventricular septum. The symptoms include dyspnea, syncope, collapse, palpitations, and chest pain. They can be readily provoked by exercise. The disorder has inter- and intrafamilial variability ranging from benign to malignant forms with high risk of cardiac failure and sudden cardiac death. Defects in TNNT2 are the cause of cardiomyopathy dilated type 1D (CMD1D) [MIM:601494]. Dilated cardiomyopathy is a disorder characterized by ventricular dilation and impaired systolic function, resulting in congestive heart failure and arrhythmia. Patients are at risk of premature death. Defects in TNNT2 are the cause of cardiomyopathy familial restrictive type 3 (RCM3) [MIM:612422]. Restrictive cardiomyopathy is a heart disorder characterized by impaired filling of the ventricles with reduced diastolic volume, in the presence of normal or near normal wall thickness and systolic function.

ab45932 staining Cardiac Troponin T in rat cardiac cells by ICC/IF (Immunocytochemistry/immunofluorescence).
Cells were fixed with paraformaldehyde and permeabilized with 0.5% Triton X-100 in 3% paraformaldehyde. Samples were incubated with primary antibody (1/400 in diluent) for 1 hour at room temperature. A Cy3®-conjugated goat anti-rabbit polyclonal IgG (1/300) was used as the secondary antibody.
Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Cardiac Troponin T antibody (ab45932)
IHC image of Cardiac Troponin T staining in human heart formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab45932, 1µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

ab45932 staining cardiac Troponin T in human fetal cardiomyocytes by ICC/IF. The cells were paraformaldehyde fixed, permeabilized in 0.1% (PBS) saponin buffer and blocked in 10% serum for 45 minutes at 37°C. The primary antibody was diluted 1/400 (0.1% saponin, 10% goat serum, 0.01% triton) and incubated with sample for 1 hour at 37°C. A Alexa Fluor® 594 conjugated goat polyclonal to rabbit IgG (L+H), diluted 1/600 was used as secondary.
