Comparative stability of alanine aminotransferase in rat plasma and hepatocyte suspensions.
Alanine aminotransferase (ALT) activity in rat plasma was stable for up to 56 days when stored at -25 degrees. High activity plasma samples were less stable. ALT activity was markedly unstable when derived from isolated hepatocyte preparations, and declined to 8-16% of initial values after 28-56 days storage at -25 degrees.
