title: The N-terminal activation fragment of bovine prothrombin. Immunological studies leading to a one step purification.
abstract: Some immunological studies on prothrombin fragment 1 from bovine prothrombin and its warfarin-induced precursor acarboxyprothrombin are reported. Based on the results, a rapid and simple immunoadsorption method for the isolation of prothrombin fragment 1 in good yield has been established. The method exploits the conformational change induced in the fragment by removal of Ca2+. The principle may be applicable to other gamma-carboxyglutamyl-containing proteins or fragments therof.
