Pefabloc® FG, Inhibitor for Fibrinogen

Pefabloc® FG binds with a high affinity to fibrinogen, inhibits fibrin polymerization, modifies the mechanical properties of fibrin clots and can dissociate non-stabilized fibrin gels.

Pefabloc® FG is added to fibrinogen containing reaction mixtures to inhibit disturbing fibrin-related turbidity, gel formation and fibrin deposition in diagnostic and preparative procedures (e. g. measurement of thrombin generation in plasma). Pefabloc® FG is also used to inhibit fibrin formation during purification and processing of clotting factors and other plasma proteins.

des-AB-fibrin 0.5-2.3 mM
