  • 产品描述：

    F9, commonly known as coagulation factor IX, is a vitamin K-dependent protein that does not respond in the acute phase. Factor IX is produced in the liver and delivered in an inactive form into the bloodstream. Factor IX is activated by both intrinsic and extrinsic mechanisms during coagulation. Factor IX, as a serine protease, cleaves and activates factor X in the proteolytic cascade that leads to the conversion of fibrinogen to fibrin and, thus, to blood coagulation. Factor IX deficiency is an X-linked recessive condition that causes spontaneous and potentially fatal bleeding.

    CUSABIO cloned F9 antibody-coding genes into plasma vectors and then transfected these vector clones into mammalian cells using a lipid-based transfection reagent. Following transient expression, the recombinant antibodies against F9 were harvested and characterized. The recombinant F9 antibody was purified by Affinity-chromatography from the culture medium. It can be used to detect F9 protein from Human in the ELISA, WB.
