| 摘要 |
The present invention relates to a troponin protein or complex of two troponin proteins stabilized in a matrix containing at least one anionic surfactant. The stabilized troponin or complex of troponin proteins is used as a control or calibration standard in assays for the determination of blood levels of troponin in patient samples that are expect to exhibit elevated levels of cardiac proteins. The troponin protein or complex of troponin proteins remains stabilized at room temperatures for at least six (6) months.
