Recognizes Human Factor IX as demonstrated by Immunodiffusion. A single positive reactivity band was observed with Normal Human Plasma. No reaction was observed against Factor IX-deficient plasma.
Coagulation Factor IX (F9) 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.Synonyms: Christmas factor, PTC, Plasma thromboplastin component
