Human Factor IXa,b

Catalogue Number: HFIXa 1080
Size: 0.5 mg

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 IXa,b.

Buffer Composition = 50 mM MES / 0.6 M NaCl / pH 6.0 NaOH
