Abstract:

The invention relates to the production of recombinant human fibrinogen (rhFib) in the milk of transgenic mammalian animals. This production and subsequent purification process is generally hampered by the occurrence of so-called ‘clots’ and ‘flakes’ in the milk which, in severe cases, may prevent the cow from being milked at all, resulting in a halt of lactation. These clots and flakes occur because of the expression of the fibrinogen protein, which is a factor that is normally involved in blood clotting. The invention relates to solving this milk clotting problem by treating the (lactating) animals with anticoagulants such as coumarins. A preferred anticoagulant that is used in the methods of the present invention is warfarin.

Abstract:

A thrombin inhibitor is disclosed. The thrombin inhibitor comprises: (1) a segment which inactivates or sequesters thrombin; (2) a segment comprising a portion of the fibrinogen. gamma. ' chain that binds to the thrombin exosite, such as amino acid residues (414-427) and amino acid residues (414-425) of the native human fibrinogen. gamma. ' sequence.
