The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
Sandwich ELISA Use at an assay dependent dilution. Can be paired for Sandwich ELISA with Mouse monoclonal [7G2] to Troponin I fast + slow skeletal muscle (HRP) (ab24464). Use as Capture Antibody.
AP Use at an assay dependent dilution.
WB Use at an assay dependent dilution.


  • FunctionTroponin I is the inhibitory subunit of troponin, the thin filament regulatory complex which confers calcium-sensitivity to striated muscle actomyosin ATPase activity.
  • Tissue specificityHighest levels observed in human skeletal muscle (e.g. gastrocnemious muscle), differentiated cultures of primary human muscle cells and rhabdomyosarcoma cells cultured in low serum medium. Expressed in C2 muscle cell myoblasts and myotubes.
  • Sequence similaritiesBelongs to the troponin I family.

Thank you for your enquiry. Unfortunately we have not determined the epitopes. However, the antibodies are forming a pair in ELISA. Recommended pair is 12F10 - 7G2 (capture - conjugate).

Unfortunately, we do not sell ab8294 conjugated to HRP. You will need to conjugate this antibody to HRP yourself in order to use it in a sandwich ELISA. ab9920 (human skeletal muscle Troponin I) should be suitable for use as a positive control (we can...
