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.
一种新型的显色和荧光底物,用于测定血液凝血因子Xa和Xa样酶的活性。根据本发明,这种新型底物与迄今公开的底物相比具有非常优异的选择性,能够特异性地测定血液凝血因子Xa。因此,本底物对于研究涉及因子Xa的形成、抑制和消耗的化学反应非常有用,也可用于测定与之相关的各种因子,如因子X、抗Xa因子、VII因子、VIII因子、IX因子和肝素。
