Purification and Identification of human Myocardial Troponin T / 中国医师杂志

ABSTRACT

Objective To obtain high pure myocardiac Troponin T from myocardiac tissue. Methods After the myocardiac tissues were homogenized and purified with high salt solution, the Sephacryl S-300HR column chromatography was employed to separate the cTnT from cardiac proteins, and identified them with SDS-PAGE and Western blot. Results The crude cTn was purified by column chromatography, and there appeared three peaks. The second peak was single component, which could react with mouse anti-human Troponin T antibody, and its molecular weight was about 34kD. Conclusions In this experiment, high pure cTnT was obtained, which could pave a way for further research.
