Hart Biologicals Factor IX deficient plasmas are human source plasma immunodepleted of that particular coagulation factor while having the other clotting factors within normal limits. Factor IX Deficient Plasma along with the other Intrinsic Pathway Factor Deficient Plasmas are recommended for use as a deficient substrate in clot based factor assays using the Activated Partial Thrombolplastin Time (aPTT).
Factor IX or Christmas Factor acts in its active form by hydrolysing a arginine-isoleucine bond in Factor X to form Factor Xa. Factor IXa also requires calcium, phospholpids and Factor VIII as a Co-Factor to be able to do this.
Factor IX Deficient Plasma is suppliied in the following kit sizes:
