Cardiac troponin-I (cTn-I) was isolated from bovine left ventricular tissue and used as immunogen. Sixteen murine hybridoma lines were produced with two of them. I D 12 and 5F4, showing a high specificity for cTn-I; both of these monoclonal antibodies (McAbs) were isotyped as IgG I with kappa - light chains. The specificity of the McAbs for cTn-1 was confirmed by ELISA, western blotting and by the ability of the antibodies to block actomyosin ATPase inhibition by cTn-I. The McAbs may be useful for human ill vivo imaging of myocardial infarcts and other pathological conditions related to cardiac myocyte damage.
