Human Factor VIIa

HFVIIa Human Factor VIIaPrepared from purified Human Factor VII using Human Factor XIIa. The Factor Xlla is removed using affinity chromatography. Purity is determined by SDS-PAGE. Human Factor VIIa reduces to 29,500 and 23,500 with the addition of 2-mercaptoethanol. Activity is determined via clotting assay. Factor Vlla, in the presence of calcium ions and Tissue factor, activates Factors IX and X to their enzymatically active forms, Factor IXa and Xa.Buffer composition = 20 mM Tris-HCl/0.1 M NaCl/pH 7.4*Extinction Coefficient (1%) = 13.9Molecular Weight = 50,000 daltonsAlso available: des-Gla-Human Factor VIIa and Factor VIIa inactivated
