Abstract

Cardiac troponin-I is a promising diagnostic marker for cardiovascular diseases. Troponin-I immunoassays rely on monoclonal antibodies, while polyclonal antibodies, cheaper to manufacture, are uncommonly used. The current study established an immuno-analytical assay using a polyclonal antibody capable of mapping troponin-I antigenic determinant. Proteolytic digestion of troponin-I was performed. Antigenic determinant was assigned by separation of fragments using gel electrophoresis followed by Western blot and high-performance liquid chromatography followed by dot blot. The antigenic determinant region appeared within amino acid sequence 30-90. This robust procedure is suitable for early prognosis of diseases, stratification of patients, and possibly individualized therapy.
