Prepared from fresh frozen human plasma. The Human Factor X is >95% pure via SDS-PAGE and shows total reduction upon incubation with 2- mercaptoethanol. Human Factor X molecular weight is 58,800 daltons. 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.
Extinction Coefficient (1%) =11.6
The above protein was purified from Human plasma units that test negative for antibodies to HBc, HCV, HIV 1/2, HTLV-I/II, and non reactive for HBsAg, HIV-1 RNA, HCV RNA, HBV DNA and Syphilis by FDA approved tests. Donors are screened for CJD.

Factor Xa is a vitamin K-dependent glycoprotein that converts prothrombin to thrombin in the presence of factor Va, calcium and phospholipid during blood clotting. Factor Xa activates pro-inflammatory signaling pathways in a protease-activated receptor (PAR)-dependent manner. Up-regulates expression of protease-activated receptors (PARs) F2R, F2RL1 and F2RL2 in dermal microvascular endothelial cells. Triggers the production of pro-inflammatory cytokines, such as MCP-1/CCL2 and IL6, in cardiac fibroblasts and umbilical vein endothelial cells in PAR-1/F2R-dependent manner. Triggers the production of pro-inflammatory cytokines, such as MCP-1/CCL2, IL6, TNF/TNF, IL-1beta/IL1B, IL8/CXCL8 and IL18, in endothelial cells and atrial tissues. Induces expression of adhesion molecules, such as ICAM1, VCAM1 and SELE, in endothelial cells and atrial tissues. Increases expression of phosphorylated ERK1/2 in dermal microvascular endothelial cells and atrial tissues. Triggers activation of the transcription factor NF-kappa-B in dermal microvascular endothelial cells and atrial tissues. Activates pro-inflammatory and pro-fibrotic responses in dermal fibroblasts and enhances wound healing probably via PAR-2/F2RL1-dependent mechanism. Activates barrier protective signaling responses in endothelial cells in PAR-2/F2RL1-dependent manner; the activity depends on the cleavage of PAR-2/F2RL1 by factor Xa. Up-regulates expression of plasminogen activator inhibitor 1 (SERPINE1) in atrial tissues. Catalytic activity: Selective cleavage of Arg-|-Thr and then Arg-|-Ile bonds in prothrombin to form thrombin.
Post-translational: Carboxylated by vitamin K-dependent GGCX to form gamma-carboxyglutamate; these residues are essential for the binding of calcium. N- and O-glycosylated. O-glycosylated with core 1 or possibly core 8 glycans. Proteolytically cleaved and activated by cathepsin CTSG. The activation peptide is cleaved by factor IXa (in the intrinsic pathway), or by factor VIIa (in the extrinsic pathway) (By similarity). The iron and 2-oxoglutarate dependent 3-hydroxylation of aspartate and asparagine is (R) stereospecific within EGF domains.
