- 产品描述
- Factor IX (F.IX, Christmas Factor) is a vitamin K-dependent glycoprotein produced in the liver. Plasma concentration of F.IX is normally around 5ug/ml (87nM) in plasma. The biological importance of F.IX is demonstrated in Haemophilia B (Christmas disease), an X-linked congenital bleeding disease resulting from a quantitative (low activity and low antigen) or qualitative (low activity and normal antigen) defect in F.IX function. In its zymogen form F.IX is a single chain molecule of 55kD. It contains two EGF-like domains and an amino-terminal domain containing 12-gamma-carboxy-glutamic acid (Gla) residues. These Gla residues allow F.IX to bind divalent metal ions and participate in calcium-dependent binding interactions. The activation of F.IX occurs by limited proteolysis in the presence of calcium by activated factor XI (FXIa) and/or by a complex of VIIa/tissue factor/phospholipid and activated Factor X between residues Arg146- Ala147 and between Arg180-Val181. The terminal activated product in either case is F.IXa-beta, a two-chain enzyme consisting of a heavy chain (28kD), a light chain (18D) and an activation peptide product of 11kD. F.IX can also be cleaved into inactive products by thrombin and by elastase. The activity of F.IXa-beta in plasma is inhibited by antithrombin and Principle of Sandwich ELISA:Affinity-purified antibody to F.IX is coated onto the wells of a microtitre plate. The plates are washed and plasma or other fluids containing F.IX are applied. The coated antibody will capture the F.IX in the sample. After washing the plate to remove unbound material, a peroxidase conjugated second antibody to F.IX is added to the plate to bind to the captured F.IX. After washing the plate to remove unbound conjugated antibody, the peroxidase activity is expressed by incubation with o-phenylenediamine (OPD). After a fixed development time the reaction is quenched with the addition of H2SO4 and the color produced is quantified using a microplate reader. The color generated is proportional to the concentration of F.IX present in the sample.Kit Components:F0017-09A: Capture Antibody, 1x500ul. Supplied as a liquid in 50% glycerol. Affinity purified F.IX Pab for coating ELISA plates.F0017-09B: Dection Antibody, 1x500ul. Supplied as a liquid in 50% glycerol.
