Product Overview
This rabbit polyclonal antibody recognizes troponin T, fast skeletal muscle (gene TNNT3) in human, mouse and rat samples and is validated for Western blot, IHC and ELISA. The predicted molecular weight is 31.8 kDa, and the supplier reports an observed band at about 37 kDa.
Troponin T fast skeletal (TNNT3) is the tropomyosin-binding subunit of troponin in fast-twitch skeletal muscle. By linking the troponin complex to tropomyosin on actin filaments, it helps transmit calcium signals into muscle contraction. It is studied as a fast-fiber marker and in muscle physiology, and TNNT3 variants have been linked to distal arthrogryposis.

Validated Applications
| Western blot | 0.25–0.5 µg/mL (Mouse, Rat) |
|---|---|
| IHC (paraffin sections) | 2–5 µg/mL (Human, Mouse, Rat) |
| ELISA | 0.1–0.5 µg/mL |
Samples with a confirmed band (WB): rat skeletal muscle issue, mouse skeletal muscle issue.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 10% SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with confirmed staining (IHC): human skeletal muscle tissue, mouse skeletal muscle tissue, rat skeletal muscle tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Conditions in the example images (IHC): heat-mediated antigen retrieval in EDTA buffer (pH 8.0).
Immunogen
Recombinant human TNNT3 fragment (Ala45–Lys251), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. Tissue expression noted by UniProt (human): In fetal and adult fast skeletal muscles, with a higher level expression in fetal than in adult muscle. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
