  • Novel substrate for determining the activity of blood coagulation factor Xa (Stuart-Prower factor)
    Patent number: 4622389
    Abstract: A novel chromogenic and fluorescent substrate for determining the activity of blood coagulation factor Xa and Xa-like enzymes. The novel substrate according to the present invention has very excellent selectivity as compared with the hitherto disclosed substrates and enables specific determination of blood coagulation factor Xa. The present substrate is therefore useful for the studies of chemical reactions involving formation, inhibition and consumption of factor Xa and can be also used for the determination of various factors associated therewith such as factor X, anti-Xa factor, factor VII, factor VIII, factor IX and heparin.
