This is a continuation of application Ser. No. 07/276,083, filed on Nov. 23, 1988, now abandoned.
FIELD OF THE INVENTIONThis invention relates to an improved method of extracting and preparing thromboplastin reagents.
BACKGROUND OF THE INVENTIONThromboplastin reagents activate the extrinsic pathway of coagulation and are the basis for the prothrombin time (PT) test. The PT test is used to screen for blood coagulation factor deficiencies and for monitoring oral anticoagulant therapy (e.g. coumadin). Reagents for PT tests include tissue thromboplastin, also called tissue factor, and calcium ions as active ingredients diluted with appropriate buffers and stabilizers. Thromboplastin forms a complex with coagulation factor VII to greatly enhance its proteolytic activity.
Thromboplastin may be derived from a variety of tissues of different animal sources. Each tissue has a characteristic...
