This gene encodes vitamin K-dependent coagulation factor IX that circulates in the blood as an inactive zymogen. This factor is converted to an active form by factor XIa, which excises the activation peptide and thus generates a heavy chain and a light chain held together by one or more disulfide bonds. The role of this activated factor IX in the blood coagulation cascade is to activate factor X to its active form through interactions with Ca+2 ions, membrane phospholipids, and factor VIII. Alterations of this gene, including point mutations, insertions and deletions, cause factor IX deficiency, which is a recessive X-linked disorder, also called hemophilia B or Christmas disease.
Applications:
Suitable for use in ELISA, Immunoelectrophoresis and single and double radial immunodiffusion. Other applications not tested.
Recommended Dilution:
Immunoelectrophoresis: 2ml plasma or equivalent against 120ml antiserum
Double Radial Immunodiffusion: Use a rosette arrangement with 10ml antiserum in 3mm
diameter center well and 2ml plasma samples (neat and serially diluted) in 2mm diameter
peripheral wells.
Single Radial Immunodiffusion: 1% in the gel.
Optimal dilutions to be determined by the researcher.
