Coagulation factor IX is a single chain polypeptide with a molecular mass of 57 kDa. Normal concentrations of factor IX in human plasma is approximately 3 µg/mL. Factor IX deficiency and lack of coagulation activity is seen in patients suffering from the innate X-chromosome linked disorder, haemophilia B.
