Stable troponin subunits and complexes

摘要

Stable troponin subunits and complexes and methods for their preparation are described. Among other uses, these subunits and complexes are useful as antigens for the preparation of antibodies, and as controls and calibrators for troponin assays. One complex comprises a modified human cardiac troponin I together with human cardiac troponin T and human cardiac troponin C. Another complex comprises a modified human cardiac troponin I with human cardiac troponin C.
