Polyclonal Sheep Purified E N
Factor IX (FIX, Christmas Factor) is a vitamin K-dependent
glycoprotein produced in the liver. Plasma concentration of FIX
is normally around 5ug/ml (87nM) in plasma. The biological
importance of FIX is demonstrated in Haemophilia B
(Christmas disease). This is an X-linked congenital bleeding disease resulting from a quantitative (low activity and low antigen) or qualitative (low activity and normal antigen) defect in FIX function. In its proenzyme or zymogen form, FIX is a single chain molecule of 55kD. It contains two EGF-like domains and an amino-terminal domain containing 12-g-carboxy-glutamic acid (Gla) residues. These Gla residues allow FIX to bind divalent metal ions and participate in calcium-dependent binding interactions.
