Bovine Factor X

 

 

 

BFX 1006                     Bovine Factor X

 

Prepared from freshly collected Bovine plasma. The protein purity is determined by SDS-PAGE and shows total reduction upon incubation with 2-mercaptoethanol. Bovine Factor X, when activated via the contact factor pathway or tissue factor pathway, is responsible for the conversion of Prothrombin to Thrombin.

Buffer composition = 20 mM Tris-HCl/0.1 M NaCl/ 1 mM Benzamidine/pH 7.4
*Extinction Coefficient （1%） = 12.5
One unit = 10 µg
Molecular Weight = 55,000 daltons

Human Factor VIIa

 

HFVIIa             Human Factor VIIa

Prepared 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%） = 13.9
Molecular Weight = 50,000 daltons

Also available: des-Gla-Human Factor VIIa and 
Factor VIIa inactivated

Human Factor X

 

HFX 1010         Human Factor X               （Stuart Prower Factor）

Prepared from fresh frozen human plasma. The purity of this Vitamin K dependent protein is determined by SDS-PAGE  and shows total reduction upon incubation with 2-mercaptoethanol. Activity is determined via clotting assay. Human Factor X, once activated via the Contact Factor Pathway or the Tissue Factor Pathway, is responsible for the conversion of Prothrombin to Thrombin.

Buffer composition 20 mM Tris-HCl/0.1 M NaCl /1 mM Benzamidine/pH 7.4
*Extinction Coefficient （1%） =11.6
One unit =8 µg
Molecular Weight =58,800 daltons
