人类因子IXaβ
人因子IXaβ
产品编号：HFIXa 1080
尺寸：0.5 mg
由人因子IX通过人因子XIa活化制备。XIa在激活后被移除。通过SDS-PAGE观察到活化。因子XIa在两步反应中激活因子IX。在第一步中，内部Arg-Ala键被切割，而在第二步中，Arg-Val键被切割。第二次裂解导致从重链的NH2末端部分释放活化肽以产生因子IXaβ。

HFIXa 1080 Human Factor IXa β
Prepared from Human Factor IX by activation with Bovine Factor XIa. This Bovine Factor XIa is removed after activation. Complete activation is observed by SDS-PAGE. The Factor XIa activates Factor IX in a two-step reaction. In the first step, an internal Arg-Ala bond is cleaved, and in the second step, an Arg-Val bond is cleaved. The second cleavage leads to the liberation of an activation peptide from the NH2-terminal portion of the heavy chain to produce Factor IXaβ.
